Footswitch jack insertion (rear panel) cancels the operation of this switch.ĬH. TUBE DRIVE SWITCH - Selects either TUBE Channel (up), or CLEAN Channel (down). Then we burn it in for an hour or so before we ship so that there are no surprises.” “We test every used amp and pedal when we buy it and bring it up to our standards before we offer it for sale. The clean channel is really a solid-state channel and does not utilize tubes, it does put out a lot of gain for an amp rated at 100 watts.

The distortion sound is quite good with lots of gain. The Distortion channel utilizes a 12AX7 tube and also has a Drive control. They both have their High, Mid, Low and Master Volume controls. This TD-752 is an early combo hybrid made after the change in ownership.įeaturing 2 channels, Distortion and clean. These amps were produced in the mid 90’s and are some of the earliest solid state / tube hybrids.īK Butler / Butler Audio known for their “Tube Driver” and “Blue Tube” pedals, sold the company to Genz-Benz. The speaker has been replaced with a non-original Fender Eminence unit. This amp is in very good condition, fully functional and cosmetically very nice. Mine are based on using Hiwatt and Fender amps with with single coil or EMG-SA loaded Strats.Used Genz-Benz Tube Works TD-752 guitar combo amp serial number 033949. The TD-X, Fet Drive, Lunar Module, ete cetera are also all good overdrives that can get something workable for the low gain TD sound - some better than others - but not the high gain sound.Īlso, opinions can vary wildly depending on the voice of the amp/speaker the person is feeding these through. Obviously the tone range is more limited, but at the settings I used on my Tube Drivers, it nails it. At low drive settings the tone is slightly different than a Tube Driver due to the active tone circuit, but it is still very close to the TD sound.Īs many have said, the next best thing is the Boss BD-2 Blues Driver (no mods needed). It's a variation on his Real Tube/Tube Driver circuits, only with NO internal transformer. Another alternative is the 1990s era Ibanez Tube King (TK999US), the US version, which Butler also designed.

It's actually much more versatile than the 4 knob TD - goes from the mid scooped TD tone all the way into Tube Screamer territory. It is basically Butler's 911 TD circuit (he designed both) with a mid range knob added, in an ugly box. The best alternative to BK Butler's Tube Driver is the old 5 knob Real Tube pedal, Tube Works model 901. Since this old thread is still going, I'll chime in since I have tried nearly all the pedals similar to the TD.
