Tone Settings And Tube Layout

The less gain you use, the more defined your tone will be!

  1. The Tweaker 88 has both a “RHYTHM” and a “LEAD” channel. You will find the LEAD channel has more gain and sounds a bit darker than the RHYTHM channel. Of course, this is not to imply we are dictating what you should play. Just giving you more Tweakability.
  2. The suggested settings above are just that … SUGGESTIONS. Use these as a starting point to TWEAK from. Turn the knobs. Flip the switches. Get a feel for what each one does. Think of each control as another color. You will be rewarded with a vast pallet of tones to choose from.
  3. When cranking the GAIN, the TIGHT switch is really useful for making the bass tighter and more solid.
  4. The less gain you use, the clearer and more defined your tone will be. Try to find a happy medium between lots of gain (more fun to play) and less gain (cuts through the band better).
  5. When experimenting with the tone controls, be aware that turning the TREBLE up and the BRIGHT switch off sounds very different from turning the TREBLE down and the BRIGHT switch on. Try both ways when tweaking the high end. You will find lower settings on the TREBLE knob result in a bit less mid range.
  6. The RHYTHM channel BRIGHT switch is tied to the GAIN control. The higher the gain setting, the less effect the BRIGHT switch will have. You can use this to vary the amount of Brightness. Set the GAIN very low for maximum BRIGHT switch effect. If you want less, just turn the GAIN control up and reduce the MASTER volume accordingly.
