Herbert owner here. I'm very happy with Horizon Devices Precision Drive. It can be dial to be very subtle and retains all of the Herbert character with a little more tightness on bottom end, or it can be dialled to be more like regular tube screamer. To be honest I think herbert sounds great on...
I agree, when I had VH4 It felt a little stiffer harder to play amp than Hebert, but it's fun to overcome that stiffness, it's just a special thing about VH4 and I guess VH2
I tested Marked 5:25, for me it was extremely disappointing amp, it didn't stand any chance against Mark IV and Mark V...
Then Bogner is a good choice, from what I know Helios is their more vintage sounding amp, so I'm not sure its going to get to VH4 VH2 metal territory. Once I had Bogner Ecstasy 4x12 cab it was very nice, but more traditional sounding. Diezel FL was tigher faster, but more stiff.
maybe other...
for me 2x12 with V30 is more squishy, with blurry low end. where 4x12 with Eminence Governor speakers is more raw, and tigher. I had much better results in band, with governors than V30.
I would wait. I had 4 Diezel cabs in total(now two), something always showed up. but l live in EU, I guess it's easier to get them here, Germany is two hour drive from me.
here is video I recorded long time ago, fist is my 4x12 loaded with Eminence governor (they similar to v30), second is 2x12 with V30.
Obviously speakers are different, but cab construction has bigger impact.
Didn't play 6L6 with diezel but it's a great tube, so no issue here, I'm sure they work as good, if not better than KT77 or EL34.
Regarding cabs, I had both: 2x12 FL and 4x12 FL. Eventually traded my 2x12 for 4x12, so I have stereo rig with two Herberts and two 2x12 cabs.
If you planning to...
it's old cab. Newer 2x12 are oversized, with different grill and input jack, Oversized 2x12 roughly 75% of regular 4x12 cab in height this one is smaller. The grill cloth I see here is the same grill cloth that I had on first diezel cab I bought, which was from 90's and made by Peter Stapfer in...
