Well, you had to go and ask, didn't you?
As you said, the basic board originally paired with the 38 was the M30. It's a good, basic board, that can do everything you need in the way of 8-track reel production. The channels sound good, EQ is high quality, and it's not any of that chincy stuff you see nowadays. Although the M-30 is a simple board, it's no-nonsene, sleek, well designed features allow you to do many things with the flip of a switch, whereas some other mixers might require you to repatch for monitor, remix, etc.
I've had the M-30 with my original 38 since 1983, and I wouldn't part with it. In fact, I have four of them! I have a 24-track that I've been scoping three M-30's to support, which if patched correctly, would do that very well.
With a board like the basic M30, although at first glance it may seem to lack features, it's an open mixer architecture, that is functionality that's only limited by your imagination, [patch-wise].
Plus, a real benefit, is that I've seen M-30's closing for ~$85-$125 lately, and that's a sweet deal, indeed.
Anyway, what do you mean, hold out for a better console? You need a mixer, at least that's established.
The M-30's one of the most basic analog mixers that's particularly matched to the 38. The 300-Series and 500-Series mixers all raise the bar over the M-30, of course, with the passage of time, etc. However much money you want to spend, man, the mixers are out there. I, for one, will swear by the M-30 with respect to the 38, and take it to the limit. I have four, like I said. I also have two working 38's, a 34, 34B and a load of 234's, all of which, IMO, are perfectly matched to the M-30.
What a coincidence,... I have four of them!
Well, last thought, is that you can hardly do better for the money than the M-30, and it's quite capable. Like I said, with patch functions/combinations limited only by your imagination, given that you adhere to basic feedback avoidance principals.
I think there's a certain in-depth appreciation I have for the simple M-30, after 20 years. It's something that might not just strike you, right out of the box. It does have 6-XLR inputs and 2-1/4"-HiZ inputs, plus TONS of I/O patchpoints, and PHONO PREAMP INPUTS. Scoped for DJ's, too. Well, a DJ could be a musician, in certain cases!
Of course, I do have larger mixers too, incl the M-312 and 388's,... er,... uh,... FOUR Tascam 388's!
[...not to mention, TONS of Portastudios! They all have mixers! Ha!]
Okay, lock me up now. I'm insane!
