For a year and a half this Guitar PCB OMG Fuzz (Roger Mayer Mongoose variant) lived happily in a nice roomy 1590B. Then somebody here got crazy and decided it needed to be stuffed into a 1590A - not really all that hard once the electrolytic caps had been swapped out for the short versions and the pots were changed from 16mm to 9mm (soldered to one of THCustoms' three pot boards). The positioning of the pot holes in the box and the board mounted LED made things a little interesting but everything fit fine after just a little swearing and bending the tabs on the DC jack. The box is a recycled Hammond - that gray patch used to be an LED hole (filled with JB Weld and sanded level). Time, weather and imagination are just not conducive to a fine finish right now so it will stay as is until work slacks a bit.
