I use the radial as well-solves a whole lot of issues!
On some outdoor gigs, I will run a pair of Special 130's.
I guess that you mean the Peavey Special 130, @Telecastoff1 ... I have one, given to me as dead, but only dirty and fuse blown !
It's a beast, indestructibly built... I do not use it very much because it is unable by construction to give a deep clean tone with deep bass, unfortunately. This is the real only point missing on this powerful amplifier.
It comes from the circuit's tone-correction / tone shaping, because the power stage and the speaker are widely able to handle a powerful deep clean bass tone à la Twin-Reverb... One day, I'll find the way to mod my Special 130 circuit adequately, I mean : without loosing its otherwise great tone.
Favorite amps to run together.

Yes, I was speaking of the Peavey Special 130 amps. Mine sure aren't lacking any bass response, but I have noticed that a few of the 4 ohm 12" Scorpion speakers were definitely lacking bass and had a tendency to be ice-picky. I run EVM 12L's in mine and have never had an issue with bass response lacking. It works for me. YMMV.
I run the pair of a Marshall JTM-612 with a Leslie G37 rotary cab as the amplification for a Helix. Yep, I'm a swirlyhead.
Ah, interesting advice @Telecastoff1 , since I have no experience with other Special 130...
Yes, I suspected the Scorpion speaker at first, but not at all : he can give as deep bass as my EVM12 and Altec 417-8H SII, when connected to a suitable amp. Conversely, when connected to an EVM12L cab, my Special 130 amp shows this lack of bass...
Would it be possible that I finally have a defective amp ? That said, he can delivers circa 160W RMS at onset of clipping at 400Hz sinus, on a 4R resistive load, so it's not a matter of power output.
I doubt if your amp is "defective". Clean all the pots and jacks and be sure all of the OP-AMPS are seated tightly...no need to remove them, just a little downward pressure with your thump to be sure they're seated tightly in their respective sockets.
