I use mine this way from time to time, but the filter is so great that it feels like a waste not to employ it. You don’t get the same amount of tone control as a Hot Tubes due to there only being a frequency knob with resonance control, and with the resonance down, the tone control is extremely slight; you can, of course, also turn up the resonance to get the half-cocked wah type tone in the demo. This works out perfectly because it allows you to get a frequency response as wide or narrow as you wish.
There’s way more gain onboard than I would ever use, and it can get a little spitty at higher input gain settings, but with the input gain set to a moderate level, it’s a great sounding overdrive/distortion that’s a nice change of pace from time to time. Also, it reacts extremely well to DI recording, which is more than I can say for any Tube Screamer I’ve ever played.
Hope it helps!
Absolutely! Once you really start integrating the control functions you realize that any parameter can really change the color pallet. The frequency and resonance possibilities are outstanding and since they have real control, you are always amazed at how totally over the top or subtle they can be. I love this box.
Well, as a fact, while designing the final Tube Zipper,
the “input GAIN” never was intended to function as a pre-filter overdrive,
but rather as a possibility to adapt low-gain pickups and other signalsources
to get “unity-gained” for clean purposes,
and as well to be able to pad down hot pickups, to attenuate them,
so as to be able to play clean even with active basses…
The intended distortion happens after the (“Pure Tube”-)filter
hitting into the built-in “Pure Tube” distortion after it,
which can be controlled with the “Drive”-knob.
The overall output signalstrength is scaled down then internally
so as not to physically “kill” any following instrument/gadget/amp,
and mildly controlled with the “master” volume-knob.
At a certain point (of course again depending on the signal source strength and the input gain setting…) the filtered/distorted signal becomes “saturated” because it exceeds the maximum clipping voltages near the power-supply rails,
and no matter how much harder you drive the input,
the absolute output-amplitude can`t get higher;
but: it will go more distorted/fuzzed the harder you drive it,
because the signal slope will get steeper,
and distortion onsets earlier…
