I’ve both and would say that the JMJ has a thicker chunkier tone with more mids, similar to a Precision, whereas the MIJ is more Jazz like, lower lows and crisper highs.
I was similar when in Knock Off, only used the 410 & 210 on a couple of occasions, the 410 being more than enough and as it was on wheels easier to shift than the 210.
My preference is as @Leonard Smalls says, you get great options that way, but my back agrees much more with @Downunderwonder - and this is what I have gone for.
As Steve Jones from The Sex Pistols said, you don’t have to be best mates in a band any more than if in a football team, you still pass the ball to the best placed player even if you don’t get on with them.
Great little amps, had one years ago and in a glam/sleaze rock band used it at rehearsals on rhythm guitar duties to make things easier than carrying full amp/head set up, worked surprisingly well, and connected up to a 412 made a wonderful sound.
Thinking about similar, I’m now teetotal (for 18 years) yet in one of my bands we have a song called Football Beer & Punk Rock, maybe I should no longer be playing it as I no longer partake in beer.
Have to admit I’d forgotten all about the JMJs (how I don’t know) but yes as in similar price range the expectation should be these will be of similar quality.
I have a few separate groups of friends, most of which are music related but one of which none of them have any interest in music at all, other than listening to it.
Yeah seen similar stuff, like straight people shouldn’t play gays etc. Gonna be pretty stuffed when the next film about a mass murderer gets written, who do they let out of jail to play the lead?
