Tools, Tones and Toys for Guitarists
Yet to build this myself, I quite like the idea behind this – I am partial to anything with bass / mid/high controls for guitar and a germanium transistor. Bonus points for also including a discrete op-amp, which I’ve been playing with lately. Before I looked at the schematic for this, I was playing around with modding a Boss Blues … Read more
While I was looking at a few Boss circuits recently, I was reminded of some of the DC filtering they use. I thought I might try it in LTspice for a look, as my oscilloscope is pretty basic, so I can’t test it properly on the bench. So if you are ever having trouble with … Read more
A classic Boss overdrive – the one that started it all for Boss guitar effects, originally sold from 1977 to 1985. This is one of the later designs that does not use the quad opamp. Kind of curious that after this, many designs used the Boss version of a discrete opamp that can be seen in several … Read more
Here’s an interesting take on the classic DOD 250/MXR Distortion + circuit. It’s pushed by a simple BJT boost and has an added presence control and tone switch. Schematic here. Easy to fit in a 1590B or 125B.
