I’ll be watching for the comments from @AB Nate too!
I’m still unsure if I’m going to upgrade my BTS to a BQC. Right now, my 6LT sounds killer with the BTS. I want to hear how the BTS sounds through my big amp, and it will be awhile until I can get my storage room cleaned out to get to my pair of cabinets. Most likely this coming Spring.

So, I’m keeping it as is, for now.
I use a Tech 21 Sansamp GED-2112 preamp in my big rig, and the eq on it’s “Drive” channel is very flexible, IMO. It might negate the need for a 3-band onboard eq. Also, it’s “Drive” control provides some excellent “grit”, and the ability to dial in the amount of it that I want. So, quite possibly the need for an onboard eq that produces a gritty tone might not be necessary.
But I still plan on buying a Euro 6LX regardless.
Take care, Mike!!!
