Modding my 7

Recommended Posts

Using modboards (checked out my guitarists ones so its all cushty) I plan to build in delay and a compressor limiter to my Conklin Gt-7 bass.

Problem is.. not enough space inside.

The conklin is already active so I will have to add a second 9v battery.

The sizes of the boards can be found on their site [url="http://store.guitarfetish.com/modboards.html"]http://store.guitarfetish.com/modboards.html[/url] under the FAQ. And will almost fit inside the existing cavity.

My problem is the boards and the extra Battery and the need for extra knobbing is restricted by the size of cavity and space I have to wire around.

So my solution was to have the cavity enlarged and (maybe) have a scratchplate added for aesthetics, the ability to add more knobs and the abiltiy to increase cavity space under the face of the guitar.

Another solution was to cram (alot) and find a way of replacing the 9v chunky bastards with a slim line batt like the camcorder ones. but I have no idea where to source them or what theyre called.


So help opinions and ideas please.


BTW Please no opinions on delays used for basses, compressors or limiters, 7 string basses, the type of music I intend to use this for. Thats for another thread.

If you want to know why I cant settle for pedals, its irrelevant and eccentric.. but I hate pedals and would like the ability to have the only 2 effects I use to be built in so I dont have to carry extra little cables and spare batteries around to jam nights and gigs etc. And for some reason pedals hate me. Every time I use them live or privately they play up.



Cheers


Ash

Have you thought about using phantom power? Doesn't have to be an XLR, can work over 1/4" stereo socket too, with the right cable. There are various options - 48V from a mixer channel, or lower voltages from dedicated PSUs e.g. [url="http://www.mtraudio.com/mtrcatalogue.htm"]MTR[/url] do one that can supply 9-24V.

I've always been intrigued by the idea of having effects either onboard, or attached on a strap (which was what the original Zoom tried to do), but the thing that always put me off was that I could never figure out how to easily turn the effects on and off while playing at the same time.

So (!!!) my question to you is how would you go about doing that?

Please, this is definitely not meant as a criticism, I'm just curious to know how other people approach this.

Matt Bellamy (Muse) seems to be intent on cramming an entire pedalboard in his guitars-
Whammy, Zfex etc.......

there used to be a muse fansite here with details on all his manson guitars, but it seems to be down.

Chris Squire used an Electra bass with built in flanger chorus, overdrive etc. in it.

Well if I use switches/pull pots either way it doesnt matter, i've come to the conclusion after much thought that essentially its no different then changing the pickup selector, or active/passive half way through a song. just a quick flick of the wrist.

Thats the best I could come up with, the other thing is, I suck at using pedals. This for me is a challenge when im playing live, so invariably youll never see me play with pedals live. I just lack the co-ordination to use my feet at the same time as playing.

However if anyone can come up with a better idea then effectively deal with it, please do.

We could be pioneers here!

I had one of those original Zoom 9002 boxes, that fit on the strap. It came with a little wired remote control that you could stick to the front of the guitar, to select between 4 presets. It sounded awful with bass, though, and not much better with guitar.

I was trying to think of the strap mounted effects...Zoom, the problem with that was seeing what was going on.

I suppose using stacked knobs would be a way around having too many controls to deal with.

Some compressors, the Demeter compulator for example only has one control for the compression, the 2nd one is to set the output, so one knob would be all you needed for that.

How many would you need for the delay ?.

I don't think the power supply would be too much of a problem, something like the Diago is only small, batteries are a bit crap for effects in my opinion anyway.

These effects, when you actually look inside box, don't actually take up too much room, so it should be possible.

How do you find your GT7, it's something I'd like to get.

the plan is 1 stacked concentric pot per effect (2 controls), and 1 switch each, unless i can find push/pull stcked concetric pot.

Also, would using just the 1 battery only affect the battery life and not performace, otherwise that is a huge step overcome.


My 7 i love. Its the only bass i can imagine gigging 1000 times endlessly without giving me crap.
It plays beautifully has a huge range of possibilities of how you can play it, let alone notes, its well balanced, solid, has a fantastic neck, well constructed and looks stunning.

Oh and as a kinda thing me and my guitarist have goin on, we like kill switches, so im gonna stick one in for the hell of it.


Thanks for the suggestions guys.

Having said that, replacing the mighty mite could be an option.


Well here's now what im thinking of as a layout, if i rewire all my pots to be concentric, i could keep all the preamp controls (not necessarily the same preamp) and only have to add the switches, just not sure where. If this would run off the one 9v batt, could save alot of time. Still not sure on the scratchplate?

Ive pretty much decided, thats how the wirings gonna be, im gonna keep the migth mite, serves me fine atm, run everything off one batt, cram everything in the cavity, replace all the current knobs, with concentrics, add the switches, and im gonna try source some purpleheart wood so I can have a pickguard matching the fretboard/neckwood.

Just havin a lil trouble findin suppliers now.

What are you having trouble finding?

www.thomann.de are good for concentrics and knobs. farnellinone.com have a huge range of switches.

I suggest you email the effects manufacturer for advice about sharing batteries. Should be OK if pickups and effects are both negative ground.

Will you wire in a bypass switch so the bass still works if the electronics go tits up in the middle of a gig?

good luck!

The electronics parts arent the prob. Its finding matching Purpleheart thats gonna be ugly. Its Either way too much or way too little. But I think I may have found a decent supplier who will give me more fitting sizes.
Ill email mighty mite people see what they think.

A bypass might be an idea seeing as this is gonna end up being some quite complicated electronics.

I think now seeing as im getting more serious, this thread may have to be moved to build section, or ill start a new thread.

I have a template now for the pickguard.

If you look at a pic of the mighty mite board the pots are ready set into it, however my plan is to remove them, then rewire the terminals to the concentric pots as planned out. This means ill be free to move the preamp within the cavity, hopefully giving enough space add the modboards.

Ill have to work out a big nasty schematic now.
