Boss ME-80 to L1
The Boss ME-80 has
- &frac18 inch Tip-Ring-Sleeve output for headphones or a recording deck. This includes guitar amplifier speaker cabinet emulation. This should give you good results with a T1®.
- ¼ inch jack Tip-Sleeve outputs for a connection to guitar amplifiers. This would not be the best connection to a T1®.
Similarly, you would use the same connection on the Boss ME-80 to connect to an L1® Compact.
