My post in the Fender Bassman 100T thread from April 2012 refers. As it was a sample of 1, that's not conclusive, maybe the one I played was somehow defective....
I'd also be interested to hear from others.
Can't seem to quote it, so c+p:
I have been a bit disappointed with the new Fender 115.
Had a leasurely test at a shop with a Bassman 100T.
Twofold intention, one - I wanted to see if it would bring anything to the table tonewise that I dont have with my SF Dual Showman (it doesnt) and two - I was/am looking for a 115 with a suitable form factor (26" wide) for my Dual Showman.
The 115 had no real lows. Going down the B-string in half tones, you could clearly hear the point, where the bottom went missing. Maybe it can improve when fully broken in, but I doubt it. Then, I started hearing some chuffing noises at medium volumes. Couldn't start taking the front off to investigate the port diameter or maybe there was some dampening inside flapping loosely... anyways... bit disappointed. Form was right, price was right, but tonewise, my Aguilar GS210 runs rings around it.
Also compared the Bassman 100T into an Aguilar DB410 and Bergantino AE212, both sounded great in combination with the Bassman. Great amp, one does need to familiarize with the active EQ section of the overdrive chanel and the gain structure when using the blend knob. I'm a bit envious at all those modern cons it has to offer, but tonewise (for my tone goals) no different to my Showman.
Just to be certain, I also tried the Aguilar TH500 into the 115 with the same results, no bottom and early chuffing. Ah well....
