right when i was younger my dad bought me a fab metal pedal. it isnt brilliant (infact its crap) but how would i be able to mod it so it would sound loads better and use less power?

Its a 20 dollar pedal. So just about everything about it is cheap. Wouldnt take much modding to double the cost of the thing. And the components inside are really small not easy to work with. Better off building something or getting a better pedal.

with the money you'd spend making it better, you could source your own parts for a better pedal. Personally, i'd trash the internals and make into a simple booster or something.
