@York Audio What I would like to see is more cabs with multiple speakers. This can be:
-1x cab with 2x+ versions of the same speaker (ie. Pre-Rola G12M-25 & current production G12M-25)
-1x cab with various speakers (ie. G12M-25, G12H-30, V30, etc.)
I know that your model is using stock speakers in the factory cab. But with some current production models (ie. V30s), this can be limiting. It would be cool if for the Bogner cab you mentioned, if it came with current production V30s & T75s, for accuracy/authenticity, and vintage V30s & T75s for improved tone. Or for the Marshall cab with G12 Vintage, you also included some vintage V30s or Mesa V30s.
I also tend to not like doing multiple speaker blends with two different cabinets. I prefer to blend speakers that were shot in the same cabinet. While York Audio IRs is my current favorite brand, the following OwnHammer combo packs have always been workhorses/heavy hitters (excuse the puns) for me, as I can can mix various speakers and their resonance/airy-ness sounds "correct", since they were shot in the same cab:
-112 DVRB
-212 Rect
-212 VC30
-412 Fman
-412 Rect
-412 MRCB
This was/is my hope when you got the custom built York Audio 2x12 "Golden" cab that you shot with the G12M-65s. If I were an IR maker, I would utilize 2 approaches:
1) Focus on the cabs: Stock speakers in factory cabs (both vintage & current production) = accuracy & authenticity
2) Focus on the speakers: Same cab + various speakers
---This can allow for easier comparison of various models of the same speakers (ie. Pre-Rola vs current production G12M-25), for by shooting them in the same cab, you eliminate the important variable of the cab itself, which can make comparing IRs hard when you're comparing a G12M-25 in a 4x12 Mar 60B vs a 4x12 MB Recto OS/Stan.
---With approach #2, you could build a family of IR packs that you could sell individually ("York Custom Cab" + G12M-25 or "York Custom Cab" + V30, etc), or as a slightly discounted collection IR pack with all of the speakers featured in in the York Custom Cab.
Sorry for the unsolicited advice/armchair daydreaming. Keep up the great work!
