HELP & FREQUENTLY ASKED QUESTIONS

SPRING REVERB II

  • If you are in mono mode and find that your output is muted in bypass, check the the mini switch on the PCB is set to β€˜M’ for mono. Check the manual to find the location of the switch.

  • In ECHOVERB mode, the subtle delay/echo can become less present with increased amounts of modulation (Layer 1 MOD). Reduce the MOD amount to gain more clarity on the echo.

    Also check the position of the L2 Micro Tune Delay Time knob. Try increasing for a longer Delay time.

  • Yes, the knob positions for the current layer are maintained / saved as you switch from one layer to the other.

LO-FI DELAY

  • Check you have not set the Wet/Dry toggle switch to Dry. In Dry mode the input to the delay channel is only active when SPLASH footswitch is momentarily held down.

ROUNDHOUSE

  • Currently the multiplier is preset depending on what the current master Speed is set to. Slower speeds will go up to x6 over about 3 seconds, faster speeds will only double over about 1-2 seconds.

FAQ

  • This is most likely caused by having non matching cables+plugs with your selected Mono or Stereo IO mode. Cables must match the selected mode. If using mono in and out make sure the pedal is set to Mono IO and use standard TS 1/4” cables+plugs. If using Stereo out be sure to use Stereo 1/4” TRS cables+plugs.

  • Colortone recommend an Isolated Power Supply providing 9VDC (Centre Pin Negative) with at least 150mA current

  • Yes, our Pedals are True Bypass and incorporate a hardware based Relay switching mechanism. Should power be lost to your pedal board the Relay will default to Bypass mode and pass through the incoming audio.

  • The faceplates are made from Stainless Steel. Clean with a basic degreaser like soap and water. Buffing clean with a micro fiber cloth will bring back the lustre of the original finish and remove finger and dirt marks

  • The β€˜Headliners’ knob caps are made from a flexible silicone. Simply line up the Line with the Dot on the knob, place one end under the lower ridge of the knob and pull and stretch over the entire face. Then run your finger around the lower lip to make sure it is sitting flush all the way around.
