Ah! The Tubescreamer pack of TS pedals! Variations of the same theme updated through the decades they are all somewhat similar and then some...
All of 'em nice in their own unique way.
I do find the TS7 the most interesting of all. Here's why;
1. Can easily sound like a classic 808 if you must
2. More flexible and practical than a 808 and TS9 because of the 2 way selector.
3. Not as bloated as TS9DX
4. Has better on/off switch reliability
5. All known mods for 808 and TS9 are applicable to the TS7
6. Not over hyped hence not overpriced.
7. Those cool "push to save setting" knobs!
The TS7 must've been a logistic and costing nightmare from a manufacturer's standpoint. Utilizing 4 seperate printed circuit boards, a smaller but more reliable on/off switch, special push push knobs and a cleaner leaner redesigned chassis. NICE!
