Welcome - Thank you for stopping by to look at our amps. Frenzel amps are very different from anything else you will find in the custom boutique amp market. They were inspired by the classic 50's-60's tube amp designs that create the "tones you know and love" but they are not clones. They have many added features and custom options not found in the original vintage amps which allows you to create your own design and your own individual tones. They have a large selection of options including custom voices, power levels, reverb, tremolo, choice of tubes and cabinets. More detailed information, specifications, photos, videos, and sound clips of our amps may be found on the individual amp web pages. Know this for sure...we love our work...and we think you'll love our amps!   ​Read our Reviews page and you will see the truth in this statement.

About Us - We are a small family owned business that specializes in building custom tube amplifiers. My name is Jim Frenzel. I am an electrical engineer and I have been designing and building tube amps since 1952. My three sons who got me started building guitar amps for them when they were teenagers back in the 1970's are now all engineers as well as musicians...and excuse me if I brag a bit...fantastic guitar and keyboard players!  Everyone at Frenzel is a master craftsman, loves their work, loves music and loves people.  With their help and a lot of input from  our "tone freak" friends, we have designed and built thousands of custom tube amps for musicians and audiophiles all over the world.  More About.

​

More Than Amps -  In addition to designing and building tube amps,  our team members are all people of faith. We use the engineering and musical talents God has given us to build the best tube amps we can, but at the end of the day, there is more to a successful and joyous life than work and business. There is our faith which calls us to follow Christ's message of compassion for one another and to try and make a difference for good in the world.  To follow this call, the Frenzel Outreach Foundation was formed as a non-profit charity to support organizations dedicated to humanitarian outreach and mission work for children in need all over the world.  For more info please visit our Outreach page.

Thanks - The world is a very large place and we are separated by many cultures and beliefs, but there seems to be in all of mankind a desire to play music and celebrate life...and we are happy to be a part of that common bond of humanity.
