    So check this out.
    I have a ampeg V4 4X12 cab. Didn't figure it out until a few weeks ago. It was bought from Daddy's Junky Music, they sold it as a Bass Cab.
    Been playing on it for around 6 months solid now.

    Not a single bassist I've met / gigged with, ever knew it was a guitar cab....cuz thats what it is, or what research told me. It was sold as a "Musical Instrument" Cab, but verdict seems to be, guitar cab.

    I have a Black Widow 1820 for my low's, and the ampeg v4 cab pulls out my highs. Its a great combo, you can hear a nice bass tone out of it, and I have no complaints.

    Anyone have any opinions on how using a guitar cab like this will "hurt" my sound? I really think it sounds great, and no one is noticing. I plan on keeping this BIG guy, but if the speakers blow I'll probaly replace them with bass speakers.

  2. Hi Troy.

    A BW1820 & V4 4*12". You have roadies? :).

    Since someone out there might die for the cab or the speakers or at least pay a good deal of money for them, checking the originality of the speakers might be a good idea.

    Using a "guitar" cab won't hurt Your sound, but may hurt your wallet.

    Replacing speakers is not just as straight forward as taking the old ones out and putting new ones in, as You probably already know, so your choices may be limited as far as the replacement options go.

    I think both V4 amps and cabs were used for both guitar and bass...

    Im 6'3", 250, and move steel all day for a living. I move them by myself :ninja: ....well the BW 1820 has wheels, so that helps lol
    I did not allready know that heh. So my gear will be fine, my bass sounds good, and I have nothing to worry about, sweet. Don't hear that too often.

    The speakers are the originals as far as I can tell. The original speakers have two wierd little prongs that come out from the cone and attach to the wall (i think its called the wall, biggest part of the speaker, the "ring" outside the cone). As far as looks can tell, its dead on.

    I saw one going for like $350.00 on ebay. Kind of pricey considering you can get the 8x10 ampeg cab for around $500.00

    I gotta say having an 18" speaker, 2 X 10" speakers (in the Black Widow that is), and then 4x12" is exactly what I was looking for tone wise. Booming lows, punchy highs, but bass you can hear down the street.

    Most of my gear is out of production, which is cool to say, but lame-ish to have. Ampeg V4 is from the 70's, BW 1820 is from the 80's ( pretty sure), and my bass is SGC Nanyo SB320 from 91. Nanyo went out of business in 93. The lame-ish part comes in when I'm trying to find out specs on gear, or get some darn customer support lol

    Thanks for the help, I'm glad I'm not doing something taboo in the bass world with the V4

    I've been really curious about those Ampeg 4x12s as well. what is the power handling and ohm rating on those, and are the stock speakers really that fragile?

    The v4 and v4b differ on the eq and switches on the front. Obviously the v4 guitar cab is very very different from the v4b bass cab

    The guts on the amps are almost identical.

    I once had car trouble, or amp trouble or something, where I could not bring my bass gear to practice. And my drummer had a vht power amp and a vht 4x12 guitar cab in his basement. And I was absolutely pissed to find how much better these two things sounded than my hartke3500 and two 410s. It was louder, clearer, and had better lows. Litterally it was bass>poweramp>cab. And it was incredible.

    As far as damage goes, make sure your impedence is all set. (I think you've got a 2ohm total load there) and I wouldn't worry about much else.

    I have a V4 4x12 guitar cab in my possesion right now that I am converting to bass. I'm replacing the original speakers with Eminence Basslite S2012's. I can not wait to see what it sounds like when it's finished. Johnk did this as well with deltalite 2512's, he says it's his favorite bass cab now. So yeah, I think it'll probably be just fine for bass.

    That V4 4x12 cab is one of the best-sounding guitar cabs ever made. Since you apparently haven't shredded the original speakers yet, you might want to think about putting some sort of crossover in the chain to filter out the low lows (since you're getting them from the Peavey cab anyway) to hopefully preserve that cool old cabinet. Or, swap out the speakers before they fail. Just because it hasn't failed YET doesn't mean that you're not going to damage it eventually running full-range bass through it.

    Sort of but not really. The V4 with the 4x12 was geared towards guitar, the V4b with the 2x15 for bass.

    Troy that sounds like a massive wall of bass. This thread may be of some use to you:
  10. ugh. daddy's has an earcandy open back guitar cab that they try to sell as a bass cab because it's 15" and only bass cabs can have 15" speakers. When I asked about it's 50 watt power handling, the dude said "its for the small amps i guess"
    ugh. ughhh.

    Internet research says it's rated for 300 watts continuous

    The back of my V4 says 8 ohms, so ....its 8 ohms =)

    Never had a problem with the speakers, in the slightest. I never dropped the cab or anything crazy like that. But when its loaded, its loaded in a pickup truck full of cabs, so im sure it takes a bump here or there in the least. No problems

    The input is the biggest problem. Apparently, it had a different input jack that wasn't 1/4" input. So people put their own 1/4" jacks on there, and the thing gets loose ALOT. Re-soddering(sp?) should fix it, if that doesn't work, might wanna throw a new one on.

    The cab was used as a "Musical Instrument" cab it seems. It was geared towards guitars, but bassists used it, and it was used as monitors as well. I cranked my SWR 750X once, and it didn't even distort. I wouldn't change a thing, but if the speakers blow, you just lost out on some cash you could of got from selling the speaker.

    This thing sounds great. Some are willing to pay 100 for each speaker if they are original, and I've now seen alot of these cabs going for around $600.00.

    If your not happy with playing through a guitar cab, or don't plan on changing the speakers, might wanna just sell it off and buy something to your liking.

    I think this things wicked though :bassist:

    Thanks for the help all. It's hard to sort through the hype and fact on this cab. People say things going both ways about me using it as a bass cab, but I dig it!

    I think if you model what that cab will look like as a bass cab with woofers, you will be sorely disappointed. I used to own one, and looked into converting it. The volume of the V4 cab only was suitable for two 12" drivers, so you would have to plug the other two holes, then calculate what your port size has to be, and add that. I thought the stock v4 cab sounded horrible with bass.
