Just curious what's the difference (sound-wise) between the original Tubescreamer, the TS-9, and the Tone-Lok version? My friend just bought the Tone-Lok version and I'm wondering if he's going to be disappointed (he's had it for a few days, I haven't talked to him yet though). He's got a Boss OD-10 too that he uses for his main distortion sounds and wants to either use the Tubescreamer as a boost, or use it for distortion and use the OD-10's boost feature as, well, a boost

He's got a Randall something-or-other half-stack but hates the distortion sound of it (it's too "metal" for him

). If he's never heard the original tubescreamer will he even care about the difference (if there is one)? The only reason he got instead of the re-issue or the TS-9 is because it was so much cheaper.
