Hi All, I've been drawn in to the Forum by my absolutely joyful experience with the THR series & the excellence of information and spirit here, most recently displayed by MegaCrasher. I owned a THR 5 for over a year. I enjoyed it so much that I decided recently to purchase a THR 10C too. I'd been seeking a good "apartment volume level" clean tone that can still crank a bit. In the course of putting my Pedalboard together, I purchased a DLS Chorus-Vib second hand that happened to be Stereo capable. When the THR 10C arrived the light bulb went on. I hooked it all up and was literally blown away by what I heard! Considering that I hadn't planned on what I stumbled across, it was like finding a magic key to a wonderful 3rd dimension of sound. Not only that, I am running it through my Apogee One via a splitter to utilize my iPad for Spotify and backing tracks/practicing & it is excels as a personal practice station/hi-fi system in this type of configuration. I started to dial in my 10C with the THR Editor as well as saving some presets both from Yamaha as well as you kind people out there that upload them. IMO, that is when the amps really start to come alive, so I decided that the extra features (still haven't plugged my Bass in but looking forward to hearing it when I do) and superior clean tone of the 10C is my thing & I ordered another one. Between the tweak ability of the amps via the Editor and pedals, the range of high quality tones is stunning. I sent the 5 to my friend in Seattle. I couldn't keep raving about how great the THR is without making him a member of the club too! He has excellent ears and also is amazed at the sound and versatility of it. MegaCrasher, that's a fantastic gift idea for your Dad for Father's Day. Having owned both, I recommend the 10C especially for his style. I bought mine from an authorized dealer on a certain auction site on best offer and got really good deals on both. These Yamaha THR amps are one of my favorite gear purchases since I got back into playing. I've had no issues with any of them yet either.
