1. Sell the JMP and the TSL and buy something that has channel switching that you can live with.
2. Buy a power amp and speaker for the JMP1.
In option 2 you can either run the FX in series but what you might consider is running them through the FX loop of the TSL, and then using an ABY box to add the JMP for gainy sounds, but leaving the clean running underneath with the fx on the clean sound. It might not be what you want, but it can be a very cool sound.
