I got mine today.Had about 3 hrs on it a/b'ing with my og x88r straight into vht 2150 to 2- 4×12s.
I'm dawless atm,so unless we settle for a cellphone vid,I'll give a quick rundown now;
I used a custom tele and custom guthrie govan. My og is 34 yrs old and values may have drifted some and I do have some premium 12ax7s in it too.
On the 88ir I bypassed all irs,etc,used effects send or main outs-they seemed the same to me.
The 88ir seems to have more gain all channels,and ch 1 is way better especially with the alt setting- I had some killer tele crunch twang with it.
The fat seems to slightly scoop the mids and loosen the low end a bit on ch2&3 ( you can't hardly hear it but u can feel it).ch3 has way more gain than any human being would ever need,but it seems all usable just like the og.
After 3 hrs I got ch 2 and 3 almost audibly matched between the new and old 88.but the knobs were way different on each.
To me,the new 88 seems to have a slight mid push in tone, where the og has a slight increase in clarity. This could be tubes,idk.
Looking thru the vents on the new 88 I think tubes are jjs.And the new 88 doesn't get near as hot as the og.
Both 88s totally shred when u kick in the high gain.I found me liking the fat off with the new 88.
The new 88 also is quieter overall.Less hum for sure.The new 88 is definitely more versatile especially with ch1 alt setting.I have to live with the new 88 for awhile yet,this is only 3hrs in.
I just wanted to see if I could tonally match both 88s up and I got pretty close.Tommorrow it be all different, idk.
I have a mezz nirvana pre and to me I think the 88s are a bit rawer.But mine mezz doesn't have the metal mod either.
Anyways,ya,I'd say the new 88 passes all the tests.Still gonna keep the og too.
