The AKG 4000 is regarded by many as a very good all purpose mic.
I have the AKG 3000 and it works nice but I'd like to get a 4000. You can check out reviews on it. I've noted in many catalogs that the 4000 is not mentioned. Once in a while it is in a catalog but it is not promoted like the other AKG mics are.
It seems that a great many mid-priced and high-priced mics all have the same round body made/assembled in a foreign land. I have one of these "round" ones and it is all right but the AKG 3000 does a better job on vocals.
So, for a few dollars more than the 3000, you can get the 4000. You can, of course, spend more but you said you didn't want to break the bank.
I have an ART = pretty good and certainly not the best. But it does a nice job.
I just got the Grace Design 101 == very nice box. It sells for about half the advertised price. Snazzy box but glitz doesn't always mean good. The Grace is a good mic pre and it is much better than the ART.
Want better? Boy is there better out there, money wise.
Tape OP usually previews around 15 mic pres per issue, as well as other zines.
So, I think you just need to do some research and see what $$ area you want to jump into.
I can't remember what recorder you use; however, it should have mic pres and they would suffice for recording. Now, it depends again, where do you want to go in sound?
I have a Soundcraft M4 (same pres as the M8), although I didn't buy it for the pres, but for routing, monitoring, etc. Anyway, I've got several pres I use for recording acoustic guitar, nothing else. Certainly, a high end pre will beat out the M4 pres. A cheap outboard pre generally doesn't.
I have A/B the following pres against the M4 pres:
Pendulum MDP-1A
Pendulum SPS-1
John Hardy M-1 TC Electronics Gold Channel
FMR RNP
Aphex 207
Rane DMS22
Digi001 pres
All sounded somewhat to incredibly better than the M4 pres, with the exception of the Digi001 pres. The Gold Channel and Aphex were marginally better to my ears. The Rane was surprisingly much better, as was the RNP (to be expected). The Hardy and Pendulum SPS-1 are dramatically better. The Pendulum MDP-1A is simply from another planet. This is not to say that the M4 pres are bad. They are decent.
I used a pair of KM184s, a Tippin Guitar (rosewood/german spruce) fingerstyle. I ran into the M4 and out throught the direct outs to avoid all that circuitry.
