Ok...so I'm normally anti-battery, but when I sub on Broadway gigs there often isn't a spare plug nearby. I need a pedal preamp that can take batteries. I need something with eq and some extra gain. I know the Sadowsky and the Aguilar Tone Hammer....anything else out there? I may just grab a Tone Hammer (used to have one and liked it), but it's definitely on the bulkier/heavier side. Thanks!
 

However, you should probably consider an external battery pack. They are easy to make. Just get a 6xAA series battery holder and solder a 5.5 x 2.1 mm plug on the leads. Load it up with rechargeable or lithium AAs. A good AA will have a capacity of about 2500 mA, which is much greater than any 9 V box battery (which is really just 6xAAAA batteries in one case). Just remember to always replace the batteries as a set.

You can even buy them pre-made.

The preamps I use like mxr m80, hartke bass attack both take internal 9v batteries, and when I use my harris preamp or laney digbeth pre I power them from a usb battery and 5v to 9v adaptor.

Be careful on polarity. A lot of these are made for Arduino which are center positive.
