I dont know if this will help.... but i use the Classic overdrive before the TS7 tube screamer and gives me nice overdrive tone for a classic sound. for a heavier sound i use the Classic in front of a MT2 Metal Zone for a more distorted sound. I like the sounds so much i use them for direct recording, band practice and live performance.... i bought my Classic for $10 and my TS7 for $30 and the MT2 for $40(used). I even gave up using my Digitech RP500(which is a fantastic piece of equipment!!!). ALL pedals were bought through GC or their online store.
