The RJM Tone Saver saved my pedal board! Just by placing it first in the signal chain (before my first effect pedal) it improved the overall feel and tone of my rig. The high end is back, as is the feel of plugging straight into the amp. But there was a bonus benefit. I recently discovered that my tuner was creating some low level noise in my rig. The RJM Tone Saver has a secondary output - good for running stereo rigs or as a tuner out. This allowed me to remove my tuner from the main signal path going to my amp and instead place it in it's own isolated path. The result - my rig is dead quiet now. Awesome!!
