OR15

Post by sizzlingbadger » Fri May 09, 2014 9:44 pm

Picked up one of these OR15's, been after one for a while. Had a poke about inside, 3rd gain Stage is biased differently from the RV / JR#4 its the same as the Dark Terror, in fact the whole amp is pretty much a Dark Terror with proper tone controls.

Treble tone control caps are twice the size of RV / JR#4 same as the DT.

Just need to get a better cab, this is one I knocked up quickly with a Greenback just to get going :winky:

Interesting! I noticed that my OR100 was quite similar to the DT as well, good to know others can agree with me on this.

How's the amp treating you so far? I like the makeshift cab!

Probably a good thing it's similar to the dark terror - I may be mistaken, but didn't you like it quite a lot?

As for the cab.... I really like it! I'd probably end up sitting right in front of it when practicing just to see the cone move....... :lol:

I did like my Dark Terror, this OR is just a bit more suited to the classic rock sounds though. Th tone stack has shaped its overall sound to be a bit more middy. I have swapped out the JJ 12AX7's for some Tubestore 7025's and this has shifted it even further into classic rock territory.

Looks great. What speakers are in the Mesa?

V30, I may try a Greenback in there though.

What advantage does the Greenback have? I've never tried one myself.

Can you share the exact difference in the 3rd gain stage? Have you noticed any differences in the bass and mids cap values?

Greenbacks are less aggressive/ modern sounding than the V30. They are only 25W too so break up better with smaller amps.

The 3rd stage of the RV is biased with a 2k2 resistor. The OR15 ( and Dark Terror) use a 1k5 resistor. The treble caps in the RV are 1nF and the OR15 uses 470pF. The fixed resistor in the tone stack is 47k in the OR15 and 39k in the RV.

That Mesa cab is a 1x12? That's the best-looking 1x12 cab ever.

Yeah, really cool cab that. If it had an MC90 and a (half) open back I'd be after one like a shot!

OR15 is nice too. Should be a great pairing! 8)

Well funnily enough I made it open back this afternoon. I also tried a G12M in there but preferred the Mesa V30 which is unusual for me. I normally find V30's a bit too bright but this one seems ok.

Wow that Cab looks good .....My understanding is that Mesa 'specially select' the V30s for the cabs which may be another way of saying 'Not all V30s (and maybe any other speaker) are created equally'

Also the other way around, some cabs just sound better with certain speakers because of the cab characteristics.

Greenbacks sometimes sound more scooped.

I like the home-made cab too. You should put tolex and corners on it.
