Kind of infamous JTM45 clone. Pretty cool build from the early 90’s made and sold by a company/builder who was later accused of sending fake checks to parts suppliers, taking deposits for amps that were never made, selling used and broken parts as new, and so on.Aside from all of that in later years, this amp is a good one.

For sale! Super huge discount. This is the last piece from a collection of broken Gibson amps I bought last year and it needs a home. DM if you want it at 50% off.

Did what I could to save this Mesa Mark I cabinet that was held together by the corner covers. Healthy dose of wood glue. Seems good now!

Happy holidays from your neighborhood amp tech! Thanks for trusting me to build you an amp, pedal, or fix your stuff. I appreciate all of the word of mouth recommendations and unsolicited google reviews. That’s how I stay in business. I’m a little uncertain of what 2025 will bring, but I do know I can count on you all to keep me sane and busy.

Best,
Bob

Anyone out there familiar with these Ei KT-90 tubes? I have a matched set of 8. Maybe I’ll just try them as a KT-88 or 6550 replacement.

Monster 8x el34 @soundcityamp you may have seen this around the shop. I finally took a morning off of repairs to get this one up and running. The dirty channel is insane. It’s for sale for a reasonable price considering the wattage. DM me if you’re interested. Also listed on my reverb page.

The debut JUDGE overdrive pedal. Based on the ODR-1 modded to have softer but more aggressive clipping, more gain on tap, a wide mid frequency sweep and powerful bass cut so this sounds great with all guitars and amps. Use the Width control to find the perfect spot to cut through the band mix. Crank to the Bass to fatten up a thin sound. Add a little grit or a lot! As with all Judge pedals, these are made by hand in small batches to expect fingerprints, dirt, blood, sweat, mountain dew stains, etc.

Sunn sorado on the bench. It doesn’t get much simpler. This is a big inspiration for the Judge S100 amp.

A boost, overdrive, distortion, and fuzz. Our take on the harmonic percolator but heavily modded and super versatile. We start with an obscure Soviet transistor to get the coolest tone we could out of this under-appreciated circuit. Available in red on brushed metal, red on white, or clear on brushed metal. You get what you get. Expect dirt, scratches, blood, sweat, and some tears as these are hand made in small batches.
