Dear Jim, How are you, family and employees doing now ? I have had the Super Vibe FM-763 for about 6 months now and have tried many tube combinations. During that time I have found many combinations all of which sound great in their own unique ways. This amps versatility is unmatched because of the very high quality components used. I am sure that you will not find this in any amplifier from a major manufacturer at any price. This amp delivers beautiful sounding overtones and harmonics, so much that I often let chords sustain and enjoy these absolutely beautiful sounds. 10 years ago I never imagined that my playing could sound this good. I mostly play with the M channel at about 7 and the F channel at 3. This gives it a very nice fat Marshall sound which I completely love and enjoy. This amp is an electronic work of art from the design stages until the final build. From this I conclude that this company absolutely loves what they do, true pros. For me the search for great tones is completed. I give my strongest recommendation to Jim Frenzel and Company as I truly believe you cannot do better anywhere else. Thank you Very Much and Good Luck To All At Frenzel Tube Amps. Donald K Bazille (Thailand)

FM763SVR Frenzel Super Vibe 763 - 1.5 years later.   Dear Jim, These days I am getting a lot of compliments on my guitar playing, but I think it is the absolutely beautiful tone that is getting the attention. I have tried a lot of different tubes in this amp and have settled on the following ; Preamp tubes are 1. Sylvania 12AX7 2. Sylvanis 12AV7 3, GE 5963. Trem and reverb tubes are 2 ea 12AX7 Shuguang and 1 Sylvania 12AT7. The rectifier tube is the original JJ 5AR4 and last of all 2 fantastic sounding NOS Tesla (not JJ) Mil Spec KT88s. I am not real sure how much my playing has improved, but this amp's tone cannot be beat.Thanks Again For Such A Superior Product!  Donald K Bazille (Thailand) 

Hey Jim - I am very happy with the amp - so far I've run a les paul and a tele through it, and it has nailed every sound I wanted it to. With the Master Volume and attenuator function, I am able to dial in any gain sound I want, and use the guitar's volume to control gain, which means I won't have to re-learn how to get 'my sound' every time I set up in a different sized room!  I can use one amp for any practice or gig I am likely to get.   Proud owner of FM-763!  Dave D.

Telecaster Guitar Forum Review - The Super Vibroverb is loosely based on a Fender Vibroverb, but with some added features. It is a 40w head, with a built in attenuator which can cut power to 1/2 or 1/4 settings, and has tube Tremolo and a tube driven accutronix reverb tank.

I tested it out with a JD tele with Cavalier pickups and a Les Paul with '57 pickups. The cabinet I played through is GK 4x10 bass Cabinet with two Pyle driver bass speakers and two Eminence Ramrods.

I am actually shocked by the versatility of this amp - in full power mode it has a ton of clean headroom and really picks up subtle adjustments to the pick attack, guitar volume and tone controls. It has two inputs, labeled 'F' and 'M,' each of which has a gain control, and a master volume that controls both. With the gain, master and attenuator, I can dial in the sound I want with the gain/master and then adjust the output depending on the size of the room, basically allowing you to choose your blend of preamp and poweramp breakup at any volume you like (well, maybe not ANY volume..)

The tremolo has rate and depth controls, and seems to be able to hit fluttery surf stuff and choppy Link Wray style stuff easily. The reverb is very musical sounding, and seems very usable at all levels.

I've played around with attenuators before, and used a few amps that had a pentode/triode function to reduce power, and all of them seemed to lack something tonally at lower settings. I won't say this one is perfect, but it is the best I've tried, and I think if I was using a lower power cabinet (my 4x10 can handle 300w) it may have been less noticeable. On the 'F' channel, it was not very noticeable, but the 'M' channel seemed to get a little more flat as I brought it from 40->20->10w output. I think this is because the M channel has a lot more Mids than the F (which is fairly scooped, as it should be). It was certainly not enough to prevent me from using the setting in either channel, in fact I think I might have been looking for something to gripe about so am not just bragging about how cool my new amp is. Because it is pretty damn cool - with a few knob twists I can go from saturated, compresssed pure overdrive to bright sparkling cleans.

It wasn't exactly cheap to buy, but for a hand-wired amp with tube reverb and tremolo it is pretty reasonable. Jim Frenzel has been very responsive to my emails, and all in all I am VERY pleased with my buying experience. It did take about 2 months from when I ordered it until it arrived, but I knew that when I ordered it, so I can't complain about that!  Despres - Tele Meister
