Hello, Does anyone know if the clean blend on the TightDrive has some high end attenuation, or does the entire signal pass through without filtering? It seems a few companies get better results by cutting some highs on the clean blend, others don't seem to make a difference. Also, if you had your pedal modded post purchase, how long did it take before you received the pedal back? I haven't contacted Amptweaker yet. Thanks!
