Tony Iommi 1970'sDevice: Zoom G1X Four Firmware: 2.00 Name on device: IommiAMP Optimized for: Guitar Amp Effects chain: Patch comments: Amp tone for 70's black sabbath. I based it around the tone at from ausbry park in 1975 because it sounds great. I have my treble booster after this, so if you aren't using an overdrive or tube screamer it wont sound right. I have my amp in the clean channel, settings all on twelve o'clock bar bass and presence which are slightly lower. If anyone decides to tweak this around/add an overdrive into the chain on the pedal, please post to this forum as i'd like to see - especially if your guitar has p90s! I use an ep les paul with humbuckers, on the neck pickup which is what tony used, not the bridge.
