Ahh the digression of an electric violinist
How much do you know the Jazz violin scene here in the USA?
What stuff you get depends on what effects you want. if you always want the “violin tone” to be there.. You need more tone enhansing effects, If you want to compete with the lead guitarist, [ele violin can do more than them
] you need a different barage of effects.
feedback will always be a problem in high gain unless you have a solid body instrument. though you can make some temp fixes with some cases less than others.
First. positioning. Do no stand next to live drums. stand as far away as possible [and from loud amps.] The band MUST understand that if they can’t work with your placment it is going to suck for the entire band.
if you get an electric get one with Barbera pickups. Stay away from Zeta! Nothing else compares. I reccomend Wood Violins.. http://www.woodviolins.com/html/home.html I have seen Krzesimir Debski from poland on a Yamaha electric, and was very impressend by his tone [the first for me and Yamaha]
IF you get a pickup I would reccomend a fishman. with the fishman preamp. IF you can get the blended w/a mic- [and have the option of turning down the mic when you go high gain] OR use your current mic with a pickup [use the mic or a 50/50 for acoustic stuff, switch to the pickup for the fun stuff.
Processors. I would get a multi effects. Boss makes good stuff, I am partial to the GT-8. IF you plan on using a lot of the amp moddlers.. AND you are on a violin, you will have a lot of separated high end noise, a MF101 works nice to warm up the sound. [or the harmonic converger with high gain].. Get one that has possibilities for a pedal board.
The mulit effect will have delay, wah, phasers, etc. Not up to Moog but will be a start [and easily switchable.] The Murf is a secret weapon. the loop station could be a secret weapon as well. Add a MF 101 in there, as i promise you with a peizo pickup you will be cursing the high ends, and frankly that is the only lowpass filter i would use on my violin, as it is musical to sut the highs with it.
start with the multi effects and a good pickup. Then expan as the need arises. Make sure you have an amp.. Plan to run direct into the sound board [less noise], but use your amp at low volumes for an extra monitor.
I you can get signal to it- the murf will work well with the microphone. you migh tconsider that.
Check this forum out for other electric violin players. you will be the 2nd one to use Moog stuff on there
