Ibanez Thermion mods

Just wondering if anyone has any experience with the Thermion. I bought one from a guy almost new old stock. The clean channel sounds absolutely incredible, the dirty channel....not so hot, even with the gain full bore.
I was wondering if anyone can recommend any tubes or mods to me. I want to get that great high gain crunch out of this beasty!

I will say however, I am an experience musician but I really do not know much about tube guitar amps. (been a bass player for eons)

Any advice, tips experience?
Thanks guys and gals!

Re: Ibanez Thermion mods

Different tubes = subtle differences and not "not so hot" to "high gain".
Never a tube swap will do that.
They have more to do with warmness, headroom and sometimes a "clear" distortion.
Swapping tubes will never make you screen WOW my amp sounded this way and now sound so different UNLESS it has old tubes that make it sound weak or like crap!
So if you want high gain you need an amp that has a high gain channel, then you could swap tubes to give its distortion more headroom, clearness or warmness the way your ears need

Re: Ibanez Thermion mods

I agree with 6. If you're looking for a better distortion sound and want to keep the amp, I would recommend the pedal route by either boosting the dirty channel or distorting the clean. No amp does it all best, each has its strengths and weaknesses, which may differ from person to person.

Thumbs up

Re: Ibanez Thermion mods

Thanks for the tips guys. Like I mentioned, the clean channel sounds fantastic!
I really do wanna keep this amp. Thought about the pedal route.Believe it or not I have a Behringer GDI-21 that doesn't sound to bad on it! Sure i'll get some flack on that one...hehehe.
Yeah the dirty channel just sounds like some kind of distorted blues type of I dunno, crap sound. Almost like there's something wrong

But onto pedals, I'm kinda looking for an combination of old Stryper meets Exodus tone. how's that for a combination eh? lol
I just want to have a good full heavy tone.
Pedal recommendations anyone?

Also for kicks I just watched a Steve Vai video on Youtube plugging for his Jemini pedal. It was kinda funny! lol
Just search for Jemini Distortion Pedal Demo if you'd like to watch it. lol

Re: Ibanez Thermion mods

old trusty boss metal zone pedal will do those 80 distortion sound.
but... I'd still prefer tube distortion from an amp. So maybe a booster in front of your drive channel would help.
a lot of people I know put Ibanez TS9 or Boss SD-1 for the booster.
Again, it's up to your taste. try them all if possible before buying one.

Re: Ibanez Thermion mods

Sounds like there's a problem with the dirty channel if it sounds like you describe. Maybe you should get it checked out, there may be a problem.

Re: Ibanez Thermion mods

Yeah I might have to get it checked out. I bought this from a guy because I heard nothing but great things about these amps. But that dirty channel was pretty dissappointing for sure.
I'll have to make a few calls around as music stores are all out of town for me.
Does anyone know anybody that has one of these heads that could give some feedback on theirs?

Re: Ibanez Thermion mods

Start by making sure all the preamp tubes are 12AX7s, in case a previous owner put AT7s or AY7s in. Other than that, I would have it checked out.

Also, the speakers/cab you are running through will have a huge affect on the tone, but not on the gain.
