I wanted to order two 15' Humbuster cables but apparently Fractal is out of that length. Would there be any problem using 30' cables between my FX8 and guitar amp? I'm going stereo into two different amps and I already have a pair of 15 footers for one of them. Fractal recommends using Humbuster cables from the FX8 out [Pre] Left to the front input of the amp, and from the FX8 Out [Post} Left to the amp's FX loop Return. If I use a 15 and a 30 for each amp to keep the running lengths the same, would the 30 work better in one application than another or is it just too long to avoid signal degradation? Does anyone know when the 15' length will be back in stock? Thanks!
