The Combo Club

Does using a guitar combo with it's stock 12" speaker disconnected and the speaker out instead hooked up to a bass cab? :D


In that case here is my 160W (@ 4Ohm) Peavey Solo Special 112 guitar combo, modded with a speaker output jack socket, used with the 12" stock build in unit disconnected and instead hooked up to a 400W 4Ohm SWR Triad I bass cab, equipped with 1x15" + 1x10" speaker units + high frequency tweeter horn, the 15" speaker unit receiving the full signal, while an internal crossover filter sees to that the 10" unit only receives the part of the signal that is between 100Hz and 5kHz, and that the high frequency tweeter horn receives everything above 5kHz of the signal, the amount of signal send to the tweeter horn being adjustable via a build in tweeter attenuator :

Hey Noiseninja, for the Triad you already earn 10 points from the jury. There will be many a word here about whether or not to accept a converted combo. You already have my vote, but the final judgment will be in the hands of our Fearless Leader, who will make an incisive assessment before passing his verdict. :hyper:

Sorry. Official combo club rules state it must be one unit, indivisible, with liberty and justice for all...
As I see it, the combo is still in one piece. If it can still be used as a guitar amp with the built-in 12" driver, I see no problem in accepting The NN as a member. What someone does with their combo to achieve their goal is of no concern to me, as long as the combo can be used as a combo...... And he has a SWR Triad .... unfortunately I do not :sorry:

I indeed modded the wiring so there is both a speaker output jack socket installed in the wooden ledge that goes across the middle of the back of this Peavey guitar combo, and a regular jack plug to the wiring that comes from the original 12" Scorpion speaker, so that at any time one can indeed use the build in guitar speaker instead of an external cab.

As for SWR Triad I I love the tone it gives me, but as far as I have been able to tell from doing a bit of internet research on it this cab seems to divide people into two groups one that absolutely hates it (I guess mostly consisting of those that either expect it to sound like a regular 1x 15" cab or expect it to be a true flat frequency response full range cab, which it is not really either) and one absolutely loving it, as said I belong to the latter group of people, but man is it heavy and cumbersome to move, as is the Peavey combo (even if still lighter than the cab).

Also the Peavey amp sounds as amazing for bass as it does for guitar, and 160W is plenty for me, it plays damn loud (the overdrive/distortion channel sounds like crap though).

Jeff and I think alike. Tweeters are for guitar players (as he ducks for cover)!
The "book of words" that comes with the R200c(and the R112cab)mentions that "using the tweeter may cause unwanted distortion". Since to me, ALL distortion is unwanted, the only time the 200c's tweeter is on is when I'm running the CD player through it on breaks. I see no reason to have a tweeter in a bass amp. Most of them won't handle or reproduce bass freqs, so why?

Ah. I don't slap(bone spur on right thumb, right there)and I don't pop-except corn, so...
 
WBB, great question and you're right, the little guy has some punch. While I thought my Micromark was too shy with the bottom end (you're only gonna be able to churn out so much bass with an 8" speaker), the CMD 101 seems to have enough to make it more fun to listen to. Though I haven't played through the 15' Player's Special, I can only imagine it's similar. My feeling is this one uses the same amp as the Micromark, but with a slightly different preamp and speaker, it's a whole new vibe.

Yes, Markbass has always been known as a more modern-sounding combo where its neutrality was a selling point. You're not gonna get the baked-in goodies you'd find in a Fender or Ampeg, but I think it has its own flavor of mid-forward and a fairly flat bottom, IMHO. The highs are smooth overall, though which tweeter you have can make a difference (piezo vs horn). Mine's the piezo, which is on the famed 121P, and it was a ratty, buzzy noisemaker that I ultimately unhooked. This one, when I run my Ampeg SCR-DI through, exhibits that same brittleness in the highs, but with both basses directly into the combo, I found it better than I expected. We'll see how the long-term goes.

MB snagged me originally with the idea that it was a blank sketch pad from which you could create your own tone from. For some nutty reason, I feel this particular combo may allow me to do just that better than previous attempts. Besides working nicely with my current pedal lineup, the tone controls are ridiculously sensitive, unlike those where you have to dime the control to hear any difference. The closest thing I can compare to is Morrighan's VT Bass pedal's controls. Breathe on them and it alters your tone! As everyone knows, I'm into the versatility and my equipment has to be able to do lots of things all at once. This checks a lot of boxes, thus the reason I decided to give Markbass another shot. So far, so good.

Thanks for asking, I'll keep you all updated.
Wow- you scored a nice one there- Thought about MB combos, but a little speedy for my present level- sadly...that JB 15” or the student model are tempting!!! :thumbsup:

I'm Comboless... :(

But your Wizardry seems potent! That’s a nice looking bass! What combo are you thinking of now?? You had TWO Ampeg at one point??? Refresh my fading memory...:unsure:

I've owned the JB 15 combo. It was very nice, lightweight, and well built. It sounded great when playing in my bedroom, but during a gig, the sound did not impress me at all. It also was not nearly loud enough, even being used as a personal monitor. At the time, I wasn't playing loud rock music either. Maybe I was expecting too much from the JB combo due to the price tag. I even bought an amp wedge to see if that would help, but sadly after 2 gigs I returned it. Not knocking the amp, I loved the form factor and overall look/build quality, it just wasn't for me.

I have been watching a lot of Harry Potter and practicing my sorcery. I accidently turned my ampeg 210 into this

:thumbsup: :drool:

Did an electric gig with my Markbass combo I usually use for upright gigs. It hung with a pretty powerful drummer on my gig tonight. This is a very versatile little rig.

oh heck yeah :thumbsup: :drool:

A casual confirmation by doing the RTFM thing confirms my Phil Jones BG-400 combo is full range: 35Hz - 15KHz. There are no tweeters. That's the Piranha drivers working as designed.

Strictly fingerstyle here, and everything beyond 5KHz is dealt with the cab sim (fridge) on the VT Bass. It's a proper low pass filter roll off at 5KHz, from all sources I can find. The HPF function of the VT Bass is much gentler and perfectly functional as is.

Incoming with the Acinonyx is a free NordyMute. With the cat bass' deep roll off filter on, plus the NordyMute, there isn't going to be anything near 5KHz to reproduce. But my combo can if I want ;)
