synaesthesia

I have built several multi band systems over the ears, and my favourite for playing solo bass guitar is a three way top, similar to a fearful, with a 1X18 sub; it is all driven by active crossovers and separate power amps. I built these for gratification and just because, .....If you are playing in a band with no PA support for instruments, (not uncommon) - this would work but in a band with a proper PA, you'd be best advised not to use a sub unless you know how to filter off the competing 'sub' frequencies. I use a 50Hz roll off and frankly I still prefer to bring out 1X18 sub sometimes, the overall sound is cleaner and the 12" driver is not strained as much. But I usually take a pair of 1X12 3 way or a 1X15 3 way, as my needs are for a bass guitar monitor, usually. Have also used a 4 band PA system, with no bass monitoring on stage, just in ears.

This is the way to do it: use a line level mixer to mix the tone hammer and the sans amp outputs, use the mixer to feed the power amp in bridged mode. A line level mixer can be any mixer, say a small 2 or 4 channel unit.

I have used one for regular weekly gigs for over a year now, in Australia and here. It lasts about 5 hours for me - gigs are only ever 2.5 hours long but rehearsals have been long, 4 - 5 hours, and its still going. My bass pedal board comprises a Boss EQ-20, a custom made efx loop switch, Turbo tuner, and a Sony Wireless. I use it for my guitar pedals & powering my keyboard in one person studio. The guitarist I worked with used a Sanyo pedal juice. I'd pick up a spare if I had spare cash.

Bought a Gramma. Used it a couple of times then made my own. Foam shop sold me equivalent density foam. Built a bigger base to fit a carpet tile approx 520 X 520. Painted the 9mm board with duratex, and glued on carpet and foam. Works a treat, just like the Gramma. Tested with a 6U rack case, 1 X 12 and 1 X 18 sub. Would have cut a monkey grip but was too lazy, works fine like this. Plain and simple.

It charges via a standard USB port, so you can charge it in the car or via your laptop; or use a mobile charger. I gig with my iPad - my pianist calls whatever tune he wants from iRealB, and I have to charge that up too. So I carry a mobile USB battery pack, not much larger than an XLR connector. How many pedals it feeds depends on the current draw of your collection of pedals that you want to feed, as it applies to any wall wart or power supply box.You have to work to your current draw and see if it si compatible, you do that with a wall wart or floor supply too. If you need more juice, you get another one. I've posted images of my bass pedal board, and I have added a Sony wireless unit to it. Still works fine for a 5 hour gig. If you want to leave yours on between sets, that's your perogative - I don't. The advantages are a quick set up and load out, my rig have never been more efficient. There are electrical advantages of not having hum associated with wall warts etc. For my guitar pedal board, I use 2 - a Volto and an Eneloop pedal juice. I think there are some 12 pedals of various current draw and it works fine. They replaced two floor supplies. There is the increasing dependence on USB charging. I decided to go with the Sony wireless instead of the Shure GLXD 16, as with that I have to charge the transmitter via USB. It is a cluttered territory now, but they all charge via the same connector and it just becomes part of the ritual. If you are moaning about having to charge a cellphone you need to wake up and smell the coffee in the early part of the 21st century. If you want to be on the comms network, you charge a cellphone, and you don't if you don't want to.

If you take a signal, split the frequencies and amplify those spilt bands, that would be bi-amping. If you take a signal out of each pickup in a 2 pickup instrument, and amplify those signals, that would be dual mono amplification. With bi-amping, any phase cancellations occur as you mix the pickups. The audio system, one assumes, is a phase coherent one. You can feed the top or low end signal to compression, modulation or whatever to a consequential benefit of retaining low, controlling dynamics, etc etc etc With dual mono, if depends, - what amps you use, and how you blend them, where you place them. Some bass players who do this mix amps, and you net result is rather unpredicatable.

Seriously: http://www.slapring.com/en/shop/productinfo/slapstrap_divine.php Have all kinds, comfort strap, levys, etc etc but bought a few of these when the prices were more sensible a few years ago, have to agree the prices are ridiculous now, but seriously best strap ever, super comfortable, infinitely adjustable in a flash, very sturdy, very secure. The 'divine' model is softer and has a worn in feel, and the normal one is stiffer like a new shoe.

I had mine die at a gig after about 5 hours or so (wasn't counting but we set up 6pm and got out about midnight) of continuous usage, but as it was feeding power to effects on the pedal board going through to the effects loop of the preamp it didn't hurt, pedalboard was just bypassed. I think it died at last tune of the night. It was I think Mustang Sally or something like that was being played and it didn't want to power the pedalboard anymore.

Most digital tuners want a separate isolated power supply if you have a fuzz or some such and you are sharing the power supply; if you share the supply this will amplify whirring digital noises regardless of whether it is an expensive or cheap tuner. You can eliminate that by using a battery or another power supply. [quote name='Beer of the Bass' timestamp='1379581016' post='2214326'] I've got one of the Harley Benton (Thomann) tuners, the one that looks like a Boss TU2 copy. I've seen them branded Beta Aivin too. It reads the B string without any trouble and seems fine to use. The only issue I've had is that it doesn't like to have the power supply daisy chained with a high gain fuzz, as it causes noise in the fuzz. That may be specific to my particular pedals though.

[attachment=147031:941502_10153405462190088_1600324444_n.jpg] Am enjoying not using an AC supply or Wallwart to pedalboard. Thought about reducing cable clutter and set up time further ; built a patch bay today for the pedal board and reconfigured it, and now it is one multicore cable to the rig (send, return, input and Preamp EQ footswitch). Might go back to using a wireless to not use a cable from bass to pedal board. The Volto has been a significant change - once I was too lazy to take the Pedalboard out to gigs and worked with a compromise to how I like it on stage, can't say I have that excuse of messy multi cable stage set ups anymore.

I got one last week and gigged with it in a 2 hour show, no issues. It powers a loop switch, a Boss EQ, and a strobe tuner. It replaced two onespot supplies. Had to use two onespots before as the tuner had an audible hum interference and that needed it's own supply or an isolated supply, and I tried about 5 different tuners. With the Volto I don't have this issue.
