I recently built a Belton reverb brick -based reverb, which I assembled in 1590BB -sized box as the reverb brick was too large to fit into smaller box. Now I got a newer model, which is drastically smaller. Fits now to 1590B:
The brick is hiding under circuit board. There is three different versions of this brick with decay length from short to long. This one has medium decay, which seems to be quite all-around -type. I also made some minor adjustments to make this less brittle. Not too many one-knob reverbs in the market. Even less in a smaller box.
Some off-topic. Last weekend I saw a line-up of a top level finnish metal musicians playing christmas songs in heavy metal style. There was two guitarists playing, and another one was playing with a budget level LTD and some Boss pedals. Guess if he was still amazing. Once again I realized that I can build and buy every pedal in this planet, and it won’t bring me any closer to that sound. I cannot obviously change my fingers. Think about that, folks.
