I've now tried the Piledriver through my Marshall JTM60 combo and my Marshall practise amp.
Through the JTM 60 it sounded very full and powerful, but lost most of that 'Tele sound', which kinda disappointed me a bit. I did roll the volume back to see if this improved things and while it cleaned the sound up very well, it was still nothing really like a Telecaster.
I had a spare 20 minutes yesterday so I plugged it into my Marshall MG10 practise amp for a laugh. For some reason, through this amp it still had the same full sound that it did before, but this time it actually sounded like a Telecaster should but with more balls! :lol:
The final test for this pickup will be at band practise on Monday when I can get it cranked through either my Orange AD30 or Marshall JCM800 2210 heads and my old Orange 4x12 cab.
I'll be sure to report back when I've given it a go :)
