Your own custom head

Discussion in 'Amps and Cabs [BG]' started by rexspangle, Dec 3, 2001.


  1. Say you had a chance to design your own custom bass head. What would it be like, what features would it have and not have. Money is not an option, but it should be realistic but also could be an idea that has never been done before.

    Lots of tubes... a pristine clean channel and a foot controllable drive blend...

    Lots of watts... more than i could concievably ever need. Two inputs with seperate gain knobs so i can plug in two different basses..

    A built in korg looking tuner, since i'm gona have to buy one for it anyway.. and while we're at it.. a power regulator so my volume doesn't vary with line voltage (and it does now) and i don't have to buy a power conditioner

    More equalization than anything out there...
    parametric bass, mid, and treble knobs
    2 seperate footswitchalbe 31 band graphic's with level boost/cut sliders with 2 fully parametric eq's on top of that. and one big FLAT switch that overrides all the eq, to see if its really making a difference for the better

    footswithcale mute too

    It has to be bulletproof, shockproof, and it has to weigh negative 40 pounds so that it balances out my rack and i can lift it effortlessly. Oh and it needs to have the blacklight thing like trace elliot heads. and lots of chrome too.
    That's all i can think of for now... i'd want one of those definately.
     
  3. Nice long brown or red hair, pale skin, brown eyes to drown in.......

    Oh wait. You mean amp head?

    I would like an all tube amp that had 5 bands of EQ, 400 watts @ 2, 4 or 8 ohms, a master volume where you could get grit at low volume, and oh yeah, I would like for it to weigh 25lbs.:D
     
  6. Hmm...about 600 tube watts. Everything in it tube...power and preamp. About 30 tubes. It would have 9 bands of EQ like my Ampeg. It would have lots of gain. It would have a borderline-overdriving sound. It would be covered in chrome. It will have no built in effects other than a rack tuner. It will have a muting mat or pad on the bottom so it doesn't take any vibration from the cabs. And...it will probably end up weighing about 600 pounds.

    4 inputs, all with their own gain and on off button, and all of them are those neutrik combo jacks (that take XLR and 1/4" plugs)
    two different 5 band parametric EQ's, footswitchable between the two
    tube compressor
    1200 watt mosfet poweramp
    all tube preamp with dummy tube stage (2xel84) with drive control, and blend between tube and direct stages


    so, pretty much, a Raven Labs MDB-1, True Blue EQ, SWR IOD, some kind of tube compressor, and a big phatty poweramp all in one thing. i know it'd be huge...


    but oh well :)

    I'd want a big all tube head, (at least 300 watts), and I'd also want to be able to get a variety of tones from as few knobs as possible. It wouldn't need to get too bright, mostly just big and warm. It would also need to have a drvie control like on the SVT II Pro. It's nice to see that a lot of people seem to like tube amps too. I thought almost nobody out there was still using them.

    it would be an SWR custom .....

    - tube power amp 500watts
    - *backup* :D mosfet power amp 1000watts
    - built in tuner and I.O.D.
    - graphic eq ( 5 or 7 bands )
    - chrome faceplate .... lots a LEDs
    - all standard features on SWR heads
    - SWR preamp in addition to the I.O.D.
    - switch to change between power amps

    thatd do it for me ......

    maybe somebody could have a built in computer for surfin TB while your guitarist is changing his "strings" .... :rolleyes: ...

    I'd want something that sounds great, weighs nothing, packs a punch and has a musical, fully parametric EQ (four bands or something would be enough). A tube-driven compressor and overdrive channel a la EBS Fafner wouldn't hurt either (both would be footswitchable), but they're not required.
     
  11. I guess there are still people who didn't see that pic. Homebuilt 155 Class A mosfet watts into 4 ohms, preamp, no EQ, 30-step power meter, forced air cooling.

    All right, the circuit board was a kit.
     
  12. Got one on the bench right now.

    I tend to build to whatever I can get my hands on for the cheapest £££:D

    It's the about same spec as Joris' excepting that it's bipolar rather than MOS (because I'd already got the '2955s and the '3055s, thus no need to buy.:D). The power amp is the evergreen push-pull circuit that I've buggered about with component types to get what I want from it.

    There'll be no EQ, unless I fit a bass parametric tone system I designed many years ago, more likely just a flat X10-ish amp for a preamp. Force cooling, too.

    I've a 500VA toroid + 4 off 10,000uF smoothers @ a massive ripple current + 2 parallel connected bridges on a heatsink (OK, that bit's overkill;)) to be wired up as and when.

    There's more than enough capacity in the power supply to run a second power amp module to run either as a bridge or, more probably, as a second chan' @ a similar output power as the first. That's if I decide to build a second chan. But I don't really like bridge circuits cos I reckon they're a bit "edgy".

    I hope it will sing......

    Embellisher, nice though it would be for mine to weigh 25 Lbs, I can't see it. This un's gonna be heavy ;)

  13. 4000w solid state with 30-band EQ..
    then hook up 2 8x10's, 2 2x15's and 2 1x18's

    turn the volume down a little, and enjoy full.. FULL bass :D
     
  14. I'm with you man! :D It would have to have a Class A power section, which means twice as many tubes of course.... and free retubes forever courtesy of the manufacturer:D

    Realistically, this amp would weigh about 250lbs, would need a 50A power service and one of those window mounted air conditioners to keep it cool.:D

    I would like a SS amp that has a dial for watts and ohms. You could dial in whatever you want depending on what you want to hook up to it. It wouldn't have anything but power, no eq or compressor. I would use it with a pre-amp and a compressor that came separately.
     
  16. hmmmm....

    david eden already made something close to my ideal head... my wt-600.

    how to make it better? a second preamp channel with eq & gain, so i can plug a fretted in one hole and the fretless in the other, and just pick up either bass and git bizzy

    without having to unplug or adjust anything
    :cool:

    A 1,500 watt combo amp small enough to fit in the storage box of my bass case. Weight less than 12 ounces and equipted with a 2" speaker offering a completely flat response between 20 and 20K able to each sound levels at or near 100 db. Includes built in wireless receiver as well as a complete line of effects and EQs remotely controlled by the pocket-size remote that fits on my keychain. And runs for six months of continuous use on a single 9V battery. Oh, and the MSLP would need to be $19.99.

    all-tube pre amp with 40 foot switchable presets. have a nice drive with settings from glass-clean to full on scary fuzz. 5-band dial-style EQ, sweepable mid, 10000 power amp non-coloring watts, able to handle down to an ultimate amount of ohms, like .5ohms or something. it would weigh about 50 lbs (i don't mind a little weight). it would have a built-in chorus, delay, reverb, tremelo, phaser (expression pedal use), wah wah, have 4 seperate inputs, have a 4/5 string button. the footswitch would have an expression pedal for the phaser/wah, and it would also have a volume pedal. thats it for now......:cool:
     
  20. easy...

    size: similar to an Eden Wt300

    weight: as above!

    eq: as above, plus 2 separate-gain inputs. Blendable drive, channel selector and mute switch from a footswitch.

    power: 300-400 tube watts preferably, otherwise 2-stage 12ax7 gain for each channel with a 1000w mosfet power section. 120v/240v switchable, with a built-in power conditioner.
