- Nice guitar
- Kemper Profiling Amp
- Boss RC-300 Looper
- Roland Cube Monitor
What kind of cable should I use on connection between Amp->Looper (2) and Looper->Monitor (3)? (Instrument Cable? Speaker Cable?)
Standard screened jack-to-jack cables. No need for anything fancy. Just the very first run, from guitar to Kemper, deserves care. The low level into high impedence of a guitar signal can be sensitive to cable capacitance. Which is a lousy bit of electrical design, but we're stuck with it.
The cables themselves all need to be screened - as in a central core, and wire wrapped round it. Exactly like a normal, regular guitar lead. The plugs will most likely be standard jacks, 1/4", but could be XLR if the equipment will take them, but for guitar eventually to normal amp., it's not necessary.
You might even get away on short runs with simple twin core, (as in speaker cable) but it's not the best, as that tends to pick up all sorts of interference. Unless you're desperate, or short of money, do it like the pros!
