Howdy TB. Trying to lessen gear by moving on the items not getting enough use, even though they are excellent at what they do. Here is the RT Electronix Ultimate Buffering System, which is a control center for all your pre-amplifier devices. Here's the info from the RT electronix website: The ultimate pedalboard interface and buffering solution! Stereo friendly! The Ultimate Buffering System (UBS) was made to negate the effect of cable capacitance on your tone while sounding as neutral as possible. It buffers your signal 4 times: Guitar Input, FX Send, FX Return(s), and Main Output(s). This places the entire pedalboard in a controlled ecosystem - governed by our bright/dark control. This control is an 8-position switch that gives you tonal control of their dry buffered sound. Buffer bypass, FX bypass (pedalboard bypass), and Direct to Amp switches give you the power to listen to every part of your signal chain individually and set your buffer sound accordingly. The UBS also includes a Volume insert (send/return) that is specially buffered to optimize passive volume pedals. This loop can be placed pre or post FX Insert. The Volume Insert can also be used as a patch point for additional effects or even a tuner output. Controls Bright/Dark Control: 8 positions switch allows you to dial in your buffer sound. Direct to Amp Switch: Bypasses the entire UBS. Buffer Bypass Switch: Bypasses Input, Output, Volume and FX buffers. FX Bypass Switch: Disengages the FX Send/Return Volume Post FX Switch: Allows users to position this buffered loop pre or post FX. Features Full I/O Interfacing: Guitar Input, FX Send, FX Return (Stereo), Main Outputs (Stereo) and Volume Pedal Send/Return. True Stereo Operation True Bypass Switching Power 9V DC Pin Negative / 70 mA The center control is an awesome tone device that alters the buffer so the tone is lightened or darkened. Very handy quick tone switch device.
