    It don't help with capacitor distortion, maybe in a instrument amplifier even then a lot of it's not that good, thanks to when mettalized stuff came around and china making like some of the awfulest sounding ones.

    No wonder why it sounded so muddy! Probably should’ve checked before using it. Thankfully, this amp has an offset adjustment, so it shouldn’t be too bad.
