HBX-AC30 - Ok you did it again. My 3rd Frenzel- this time the Sweet Little 15/30 In a word "Stunning" The incredible clean clarity, overhead and flexibility has me stammering. I have been hunting for a few years for a mate to my vintage ES-335 and bought this one guessing/hoping it would be a match the way my other two FM-5E3 SD "Super Deluxe" amps match up to my Telecasters and I couldn't have been more right. Punchy, in your face presence, bell tone sustain, same killer tube magic but a new voice in the stable. The 335 is out of retirement! Keep up the good work and thank you again. Leon T. (Oregon)
Hi Jim, I just got back home from university yesterday and had my first chance to play the amp you built for me during the summer. It really does sound great, I couldn't be more pleased with the amp. I'm sure as I play it more I will fall even more in love with the sounds it is producing! Many thanks for your first class product and excellent customer service, I look forward to many happy years with this amp.God bless, Andrew H. (Scotland)
Hi Jim, My Sweet 15 arrived today, safe and sound. I got it up and running and have played it for 45 minutes or so. My initial impression is wow, what an incredible range of tones this thing has. I haven't attached my pedal board to it yet. I was just playing it straight and dry with a strat and les paul. Lots of exploring to be done here, but I can tell already that it has incredible clarity of tone. This amp is really going to cut through the band mix. -- (9months later) I have really been enjoying my HBXAC15 over the past nine months. Thanks, William E. (Canada)
Hi Jim, I am from far east, Macau. I am a happy owner of FRENZEL "Sweet Little 15" for more than 5 years & I really like it....by the way, a guitar technician came to fix my guitars yesterday, he said my HBX-AC15 sounds very nice & he wants to get one too. Matias L. (Macau)
Hi there, Just received my order for an HBX-AC15. I just wanted to say how impressed I am! The build quality is incredible and the tone is off the charts! Just had a moment to plug in my Telecaster and WOW!!! Blew me away! Thank you so much for the dedication to supreme quality! Money well spent!!! Kind regards, Gord H. (Canada)
Hi Jim, Finally the amp has come! Hallelujah! I have listened it and I like very much. It is a great amp! Best regards from Adrian N. (Spain)
Frenzel Team - Thanks so much for the Sweet Little 15, the best tone I have heard. I have owed many, many amps. Jonathan C. (California)
Howdy. the HBX-AC15 was delivered today. Yes, you guys did great. Thank you. I had to wait a little while to get it home, and it will take a little while longer still to try a couple of different cabinets and with various guitars. My first reactions are only positive. It's terrific, and I suspect I will continue to find great things about it. I really like the implementation of the controls and the way gain structure is set- not too much, not too little. The push-pull pots are a great and highly usable idea. Love it. Great work! Thomas C. (California)
Hi Jim, I can not say enough about the quality and sound of the Sweet Little 15 and the Retro deluxe that you recently made for me. Every time I plug these in and get such inspirational tones with ease, and the value provided, WOW, Thanks, Mike H. (Victoria, BC Canada)
HBX-AC15 - Hello, I just received my HBX-AC15 amp yesterday and I'm very happy with it! Brian P. (New York)
Just blown away! Proud owner of a AC15 HBX ! Tone,tone,tone!!! Many thanks to Jim and the whole family! I waited on purpose to see if this amp was gonna make it thru the "Honeymoon phase" before posting a comment.Safe to say its a keeper! The cleans are perfect, the dirt channel is old school and there seems to be quite a bit of tweaking for various shades in between. To be honest, I haven't felt this good about turning on a amp and plugging in my guitars in a long time. Keep doing the fantastic work you good people do! Dan F.(New York)
Hi Jim, I am getting up to speed with this amazing "little" amp of yours. First let me say that a friend of mine that has quite a bit of amp experience was amazed by the soldering and layout of the AC-15. Very clean and impeccable were the words he used. I saw it for myself when we took the back off. As to the tone, my friend, a jazz guitarist, spent almost an hour with me exploring the tones that this amp can produce. I bought the amp thinking AC-15/30 jingle jangle Beatle's type tones with single coils, but this amp can go well beyond that. With 5751's in the gain and driver locations, this amp can produce warm almost acoustic type tones with channel 1 and a 1985 standard Gibson 335 guitar. With channel 2 and low gain and master levels there was definitely Larry Carlton type tone happening. The compression of the sound/tone was well separated and quite pleasing. Richard S. (Pennsylvania)
Hello all at the Frenzel Magic Kingdom, I have been plugged in to my HBX sweet 15 since I received it last week and it has exceeded all my expectations! What great tone at any volume on the dials. very warm responsive goodness with plenty of fang when you want it. I'm shedding pedals because of this beauty and now must consider also having a super delux plus. I was just imagining those two running together and damn near passed out. Thanks again - swooning in tone, Philb of Sparrowbox
Hey Mr.Frenzel! I've really been enjoying my 2xAC-15s since their arrivial! I've been doing some "stereo solo" guitar recording.Miked "Raezer's Edge"speaker cabs and direct out each running into a seperate Collins 212-pre.The tracking signal routes into a old four chanel"Collins 12-Z"broadcast mixer modified into a four channel stereo recording mixer which busses to a Ampex 351-2-track stereo. Pretty simple but it's working fine.Your amps are great and very tonally modular.They track great and record with real nice clarity and defination.So thanks a lot for a great product. I truly believe your products and services reside at the level of best quality and value to be found within the audio-electronic tonal production industry.This is my opinion, but it comes with many years experience. Respectfully,Frank P. (N-Cincinnati)
Hi Jim, last year you built a Sweet Little 15 amp for me. I love it. It sounds great, and is quite versatile. I'm pairing it with an ear candy sovereign cab loaded with a tone tubby alnico 12". Ps...just got out of rehearsal with my arena-hair metal cover band. The amp was sounding phenominal. Had the presence knob pulled out for NNFB, which allows the amp, in my opinion to get closer to a Marshall SS rect sound. The Sweet Little 15, thru one 12" tubby sounded like a full stack. No problems hanging with a SVT...and its tone was full and blooming. It never ceases to amaze me. Many thanks, Tony D. (New York)
Jim, Every time I plug into the HBXAC-15 I am amazed at the tone. It has a chime to it all its own. The Boost channel has that classic Vox sound, but it is so much better. It is hard to describe. You guys pegged the sound on this. Do not change a thing. Mark H. (Texas)
Hello Jim and Team - Got it. And got about 2 hours to myself this weekend to work out on the new Hotbox AC15 - LOVE IT - and I haven't even scratched the surface; all I did was plug in a guitar and play this amp through my Bogner Cube for about 2 hours; no effects, no nothing.... This amp sounds so damn good, I'm not sure that I need anything else. Thanks!! I'll be sending you a more thorough report later. Suffice it to say that I CAN'T WAIT to take it out on a gig...Best regards, Kent A. (Virginia)
Jim, Wow! No wonder you are swamped. Jim. I own some of the best amps in the world, and have been playing for 44 years. I just got thru running your amp thru its spectrum of tones. It was worth the wait! I discovered a few years ago that it doesn't matter whose name is on the instrument, but rather what kind of person built it, and how much of themselves they were willing to put into it. Obviously you love what you are doing, and you have put your heart and soul into the design of this amp. I hope you dont get too busy cause I'm already looking forward to trying some of your other amps. It's hard to put a price tag on an instrument with a soul, but you have the best bang for buck out there in my opinion. Carry on brother, David R. (New Mexico)
Thank you Jim for building a wonderful sounding amplfier, you are a sound-craftsman and I am truly enjoying playing the heck out of it! Tony P. (California)
I really have not heard an amp with as much chime and be as thick as it is. An absolute alchemy of parts and build. I've got 2 RCA 12Ax7s, 1 Sylvania 12AX7 and Mullard EL84s thru a Red Fang and a ToneTubby Paper cone that was reconed by Weber in a 2X12 pine cab. The wiring is absolute art. Beautiful clean construction. Just beautiful. Thanks Jim for making this amp with my transformer and making it so nice. I am most grateful Rob F. (North carolina)
Hi Jim, I had a chance to play one of your HBX - AC15 amps recently and I was very impressed. I've always thought of the original VOX as sort of a one trick pony, but the HBX-AC15 amp just had a spectacular range. The Negative Loop(NNFB) switch really proved to be much more useful (and less gimmicky) than I expected as well! Dave D.
