As a follow up...
I swapped the Celestion Blue with a Warehouse Speakers ET65. While the Celestion sounded good, it was just a bit too spiky on the high frequencies in this amp, so I pulled an ET65 from a 2x12 cab I had and gave it shot. I must say that this is a really good pairing, especially in 'tude mode. Don't get me wrong...it delivers in tweed mode as well. The ET65 is just smoother overall.
What I really like about the Tramp is how touch responsive it is. Even with a TS-9 engaged, rolling back on the guitar volume and/or using a softer attack on the strings really cleans things up. I've been using Lace Sensors on a strat as well as Fralin tele pickups on a parts-Tele and they sound great...clean to really good grit, especially with the Red Lace Sensor. On the other hand, pushing the amp with a high output humbucker almost sends it out of control. I have a frankenstrat with a Duncan JB Jr in the bridge and it sends it over the top. Still a great tone, but almost on the verge of meltdown in 'tude mode.
The Tramp is a great little amp capable of wide variety of tones. I've found that my TS-9 is a perfect addition and opens up the possibilities even more.
At some point when I get a little free time
(when will that happen!!) I'll get some videos posted, or at the very least some clippage.
