Guyatone OD2 Overdrive PedalThe OD-2's circuit is based on the vintage "tubescreamer" design with a few changes that offer marked improvements. The OD-2 features the JRC 9449G IC chip ? the in-line equivalent to the legendary JRC 4558 IC that was a key element in the sound of the original tubescreamers. This IC is smoother and less harsh-sounding than other versions, giving the OD-2 the same warm, tube-like voice as a vintage screamer. guitar fx box |
