Overview:

The Amptweaker™ name points toward the design goal of making products that allow the user to tweak their own amp tone.

Another repeating theme heard over and over was multiple pedals....so this led to the idea of adding an effects loop to the back so you can add whatever you want to this pedal. And there's a Pre/Post button underneath the pedal so you can move that outboard effect to in front of or behind the TightDrive. When you bypass the TightDrive pedal, the other effect or effects will be bypassed as well. This feature is great if you want to further tweak the distortion tone with an EQ in front of or behind it, or to add compression, or a delay.

Other Tips & Tricks:

  • Effects like compressors, treble boosters, wah pedals, and octavers tend to work best with the Effects Loop set to Pre.
  • Effects like delay, reverb, EQ, chorus, vibe/tremolo, and most others tend to sound best with the Loop set to Post.
  • Try putting an EQ in the Pre/Loop, to experiment with varying distortion feel, similar to the Tight controlʼs affect.
  • To REALLY tighten up the attack, put a noise gate in the Effects Loop of the TightDrive, and set the threshold high.
  • By using very low gain/volume settings, the TightDrive can convert your lead amp tone to a crunch rhythm.
  • For a really dark singing clean tone, turn the Tone and Tight fully down, Volume up and Gain about halfway.
  • Select Pre/Effects Send to use it as a switchable ʻcleanʼ send to another effects chain, tuner input or amp.
  • Select Post/Effects Send to use it as an auxiliary send to some other effects or amp AFTER the TightDrive distortion.
  • When using extremely high settings on the Tight control, you might need to increase your ampʼs bass control.
  • Try putting a parked wah in the Pre Effects Loop for a cool mid-boosted tone.
