I have a lot of pedals and the diference between my guitar pluged directly into my amp (tele with a blues deluxe)and pluged trough my pedalboard into the amp is really huge....negatively huge...the tone suck with the pedals was just too big...high freq cut, muddy bass freq, and dull overall sound. the cables i use are not the best but they are not the cheapest, but too many true bypass pedals and cable lenght have thier consequences...that was good enough for me to get a buffer and i got it...this little and not so expensive thing was the perfect solution for my problem...no tone suck, high's are back, the tone is clear and sparkly and no noise added. It's really small, ultra simple, 9v dc...excellent!
