I cannot find a sound on one that I can't match with the other. I should add, perhaps, that both of these pedals are USA-made, so I don't know what differences might be heard in the newest, Chinese-made Rats.Īt identical settings, I hear a little less agression out of the LM308 pedal: Thinner sound, lower volume, less distortion.

By nudging the distortion knob just a bit (maybe 1 hour's worth) and the volume knob a bit more (between 2 and three hours) it sounds so much like my other Rat that when I switch between them without looking, I can't tell a difference, much less begin to guess which one I'm hearing. That's running straight out of the pedals into the preamps on my recording interface (playback through Event TR-8s). BTW Erik, that DS-1 I bought off of you a couple of months ago has become the pedal I use to goose the Rat into fuzzier territory. I've got a couple of actual fuzzes on the board, but that DS-1 is seeing a lot more use for the noisy bits than they are. Op amp changes are subtle, and usually don't change the tone of the pedal per se. They do more for changing the dynamic response of the pedal. For example, with one op amp you might be able to clean up the sound by picking lightly, but a different op amp might distort regardless of pick attack. I've never heard an op amp swap that changed the fundamental tone of a pedal. If you want to change the tone, swapping capacitors is the most effective thing. Changing the clipping diodes makes quite a difference as well.Ī lot of people like to put red LED's in their Rats for clipping instead of the stock diodes, but there are hundreds of possibilities there. In a circuit like the Rat, the op amp makes very little difference. The other components around it influence the sound a lot more.

Heck, swapping out the diodes will have a greater impact as Matt stated.Ītwood the man from mars pdf free.
