The JMPGuitars Tremolo TMB Reverb Tube Guitar Amp

JMPGuitars Tremolo TMB Reverb Tube Guitar Amp

I created the tremolo TMB amp’s circuit design based on a request from a member on The circuit came out so nicely, naturally I had to actually make one. After hearing it, I’m guessing I’ll be making more than one.

Here’s some improvised mediocrity to demonstrate this amazing guitar amp. The tube reverb and tube tremolo are built into the amp. The only FX pedal used in this demo is an Eventide Rose Delay Pedal in a few parts.

The first part of the demo is with an amazing @knightroguitars “Pioneer MS8” and the second half with a nice @kieselguitars HH2 (customized by me) ;).

Capacitor Break In Box UPDATE

To recap, the capacitor break in box is a small project I made to help break in, or burn in, capacitors for use in guitar amplifiers and other projects. This can be a very helpful tool if you’re building guitar amplifiers. 

Capacitor Break In

Some brands need break in more than others. For example, SoZo Caps say on their website that their caps need about 100 hours of break in time. When I build with their caps, I want the amp to sound as good as possible from the start; first impressions are everything, right? Continue reading

Custom Audio Patch Bay

I needed a high quality patch bay with specific ins and outs that wasn’t available (at least not for under $1000). I thought that price was insane until I built one. As stupid simple as these are, it’s a time consuming process. It’s still ridiculous, but hey, if you can get it…
