Im thinking about adding some stuff to mine give me something to mess around with. Right now i only have the channel switcher for my amp, a t-fuzz pedal which is an amazing boutique fuzz pedal made by some guy out of italy, it has a high and low pass filter swtich on it which goes from bowl shaking to total buzz saw sounds. I have a sans amp bass driver but thats pretty much defunct now im playing through an all tube head. I would like to add on maybe a cool delay unit to make crazy soundscapes between songs, but other than that im not too sure. I want to avoid multi effects though. so yeah, what des everyone use?
