Repairs to a Roland Boss GT-8 Guitar Effects Pedal

Hi - recently got a broken GT-8 to try out. It had a fine crack on the PCB which caused lots of buttons to stop working and took out a 5V regulator. Didn't have a direct replacement regulator so plumbed one in temporarily (now that Christmas and new year has been dispensed with, have received a proper one).

Rather than link out the tracks at the crack, I connected a wire to each end of the break since you can solder to proper solder pads on IC's or components which are much more reliable. It took a jolly long time - but works great now.

The sounds are great - the best bit so far is having 2 parallel amp simulators - so you can have one doing the basic guitar sound and the other with distortion etc mixed together.

Here's some photos:

The crack is horizontally across the centre of this photo - this shows the wire links I've added
