The 1 SPOT cannot be used to power multiple LINE 6 ToneCore Pedals, possibly due to inadequate power supply filtering in the pedals. A 1 SPOT can be used with one Tone Core Pedal with only a minimal amount of noise. More than one Tone Core pedal on a daisy chain causes too much noise for practical use. We are currently checking into this matter further to see if we can come up with a solution, maybe even with the help of Line 6. The 1 SPOT will work noiselessly with almost any other effects pedals, even the larger Line 6 Modeling pedals.
