Firas, your experience with the Princeton makes sense - itās just an amp, not a modeller, even though itās a solid state imitating a tube amp. The fender amps were mostly known for their clean sounds rather than overdrive, so youād need pedals etc.
Your questions, which Rob and Rob have also answered somewhat.
Attenuation is not an issue - attenuation is really a valve amp thing (or a modelling-as-valve thing). Volume & Gain control the modelled amps controls, master controls the speaker output itself independently. Yes it sounds good at low volume.
I use the XLR line out almost every day. Itās permanently hooked up to my Focusrite interface. In fact, I only use the amp either via its speakers or the focusrite. I might have plugged headphones directly into it a long time ago, although now if I use headphones itās via my Focusrite. I havenāt used itās USB out.
The XLR out uses speaker cabinet modelling. So itās the sound of a miced amp, not the sound of a raw line out. Similar concept to what youāre hearing through the speaker, thatās also cab modelled.
Quality of XLR out is good, all my recordings have been via XLR out.
I used the bluetooth streaming for backing tracks a couple of times, but I find it more convenient to play backing tracks on my PC rather than via the amp.
Thanks dude, and cheers for the likes you gave me
Yeah, the footswitch is awesome. I have one on my GTX-50, really only ended up with a GTX50 instead of 100 because I found one for sale lightly used on ebay pretty cheap, from an older gent that had bought it and then had to move into a retirement village.
Here is where we differ a bit, I use the footswitch & presets a lot, but I also am constantly tweaking and setting up new presets. 99% of the time I use the app for it rather than physical controls.
The only crap thing about the Mustang GTX is that the app is mobile & iPad only. So you canāt use your PC to configure the amp. I would find that more convenient.
Yep, sure can, I have that and used it for the dive bomb in my Lonely Boy cover. The EXP-1 is built like a tank. I donāt use it much though!
