Janky-A Rigs of Doom

View attachment 3741922 Fellow Bassists:
I submit for your consideration a truly janky Peavey cabinet that I didn't know I wanted and certainly do not need.
It's a Peavey 15SC, only manufactured from 1986 to 1987. According to Aged Horse its, "Was a very short lived box from the 1980's, big, heavy, moderately efficient but there were so many better products on the market (including other Peavey products). Direct radiating with a horn loaded port (kind of) using cosmetics of the SP-1 and FH-1, but with the driver direct radiating for vastly better mids (better for a bass cabinet) which sacrificed efficiency which the horn loaded port (or scoop) tried to help. This type of cabinet fell out of favor by the mid 1990's".

Craigslist Free Peavey Find: What The Heck?

It was a Craigslist free ad and I was bored and curious so drove an hour in the rain to find it sitting under the eaves of some squat little shed next to a lake. The area was covered in what appeared to be bat droppings which included covering the top of the cab. The first push of the cabinet revealed that there was a fair amount of water inside the cab and tilting the scooped cab made obvious that said liquid was pretty foul smelling, like urine.
At this point I of course needed to pause and reconsider the whole proposal, should I load a wet smelly cabinet that I didn't need or want all that much into my clean car? At this point my wife who wanted to get out of the house and who came along for the ride and who is generally sensible expressed her horror and displeasure that I would consider putting it in the car.
Tipping the cabinet in every direction did dump a quart to a half gallon of noxious liquid out but it was impossible to really empty it out.
We'll skip any further details of discussions or the hour long drive home but here's some pictures of what truly must be one of the jankiest janky rigs possible. It's been cleaned up dried out, decontaminated to the best of my ability and the car boom box driver replaced with an appropriate Black Widow driver.
It sounds pretty good but is tremendously heavy.

It's begging for a logo on the grill (Cheesy sample below)

Is that the top of the Choadhammer brutally sub-photo-shopped onto an Ampeg grille?

Sometimes I get thinking about making my TKO into a head. But I think a lot of what I like about it is that speaker in that box.
If I remember correctly we've got the same TKO 115 (teal stripe, BW-equipped). It's a nice little rig.
 
Mine's teal-stripe, but has a Scorpion, not a BW. I've read some posts that were not in favor of the Scorpion 15 as a bass speaker, but I like it...at least at that power level.

What I really like about it is, even though it's listed as 40 Hz-2kHz, in practice it's a bright enough speaker to put across a pretty beefy twangy just-past-clean guitar tone too. I can even get a useable lap steel tone out of it, but that involves a pretty sloped-up-and-to-the-right EQ.

I remember you liking yours for guitar. That big Peavey rat fur box of mine, shown a few posts back, has a Scorpion in it and I like it a lot; it even handles a detuned five-string well. I should have a similar cab (tolex, Black Widow) to compare next week.

This SP5ti PA cab lives in our practice space and has a dead horn. The low side feeds an 8 ohm Scorpion 15 like the one in my TKO. It occurred to me that in this phase of my jank bass growth I was feeding this one with about 130 watts from my old power amp and it did okay. Not sure if any of the TNT130s/150s came with Scorpions, or if they were all Black Widows.
 
I don't have any pictures, because it was about 20 cell phones ago, I don't take cameras that aren't phones anywhere but on hikes/bike rides, and I didn't (still don't) own a computer. Some friends and I formed a heavy rock band, God, must've been at least 12 or 14 years ago now. We were all broke, some of us in various stages of addiction and/or recovery from it, and I had a ridiculously (at that time, to me) powerful and valuable rig in the form of a Hartke 5500 head, rackmounted with a fancy compressor, tuner, power conditioner, fan panel, drawer, the works; and matching 4x10" and 1x15" Hartke XL aluminum cone cabinets. Sounded great, was about twice as many watts and pounds as I ever needed, got lost eventually anyway.

Being young but not TOO dumb, and knowing that the place where we practiced (a repurposed garage behind our sketchiest member's house, which was known to any number of sketchier-still acquaintances of his) wasn't exactly a vault, my best friend and guitar player bought, fixed up, and sold a 1968 Plymouth Satellite and used the profit to buy a whole bunch of ratty but good sounding junk to leave there so instruments were the only things we toted to and fro.

He came up with a Crate 50w tube head and a homemade rat fur 4x12" cabinet that was loaded with pretty nice (cast frame, anyway) EV speakers. I amalgamated a somewhat ridiculous combination of a Peavey 300W Mark III head and matching 2x15" cabinet, a Rogue 120W 2x12" guitar combo with Eminence speakers and no grille, like a six-million-band generic stereo EQ that I used to separate my signal into wet/highs and dry/lows with highs going to the guitar combo and lows to the Peavey, and a Peavey SP2 PA main as an extension cabinet to the guitar amp, haha! Looked ridiculous, was inexplicably not on fire at the end of every practice, actually sounded pretty good.

Never got stolen or otherwise molested, and I gave the whole shootin match to a bass playing friend who had his rig stolen from under the topper of his pickup some years later. I'm sure wherever the Peavey is, it's still running just fine.

Dude !! i remember that cab.
pretty cool you already got that loaded with a black widow.

as far as being " short lived" the remark was generalized by agedhorse so it doesnt apply to much. With Rear horn loading in general.
Horn loading picked up in the late 1920s for movie theater sound. Huge horns made 6 to 20 watts of power to provide sound for a theater.

Far as actual rear loaded horns JBL C550 picked up in the 1950s
so we are talking yes a very " short lived" 70 to 100 years for loaded horns being used

far as Peavey they had loaded horns from the late 1960s all the way to the 2000s
so yes assume 40 years to be short lived lol

yours is super rare glad to see you got it janking away :)

You were the person who correctly identified it as a 15SC right off the bat. Or bats as the case may be.
I wasn't sure I was going to even "restore" it but I found a Black Widow model 1503 on Craigslist for $68 so I figured what the heck. I guess that model was intended for a rear loaded horns?

Great thing about rear horn loading is you get a little of both worlds. All the mids and highs from the speaker itself and the horn adds little extra bass or mainly mid bass peak.

you could essentially use the 1502 , 1503 or 1505 for your cab

Peavey has a good description on its website. I wouldnt say 1503 is super rare but you see the 1502 and 1505 more often in bass or keyboard amps.
1502 had good highend and senstivity was med length coil. 1505 was longer length coil. 1503 sat right in the middle far as i remember.

I rented Peavey equipment in the 90s , i think remember seeing 1503's in earlier mid 80s cabs when they used butt cheek looking horns for midrange.
later on Peavey tended to use no mids and used a 15" with a much larger tweeter horn that was crossed over lower to blend well with the 15"

pretty much all the 15" widows had good mids and highs, and if you pushed them hard had a very distinct nice widow bark to it.
Im picking up a few for a upcoming 2x15 project

Thanks for the information.
As a teen I was fascinated by both rolled and folded horns and more especially those butt cheek looking horns.
