I bought an amp and liked it so much (about 8 watts ) that I found another one just like it. How do I Y the 2 amps together? Do I just buy a Y connector and plug my mic into it and then 2 more patch chords and plug into each amp? Will I lose signal with the Y?
If I do this would I just expect a spread out sound or is it equivilent to like a 12 watt to 15 watt amp in loudness?

Just curious....I dont need to run both in my house but wanted to know if there is any benefit playing out or it is a waste or even if anyone ever thinks of doing this.

Iv'e had good luck with a Morley pedal "A/B foot switch".
I posted a question to Kudzu runner of what brand "passive splitter" he uses but I didn't get a reply.

2 small amps together can sound great--not sure if the volume is additive, ie 2 8 watters=1 16 watts, but they do have a room-filling quality--Adam credits the wave front created by the separation of the 2 amps. A passive splitter will definitely work, but you will lose some signal, and there's the possibility of a ground-loop induced hum. I prefer to use my Jayphat (an active DIY impedance matching box discussed elsewhere on this site and others), which I made with 2 outputs--it provides a boost to the signal which compensates for any loss by splitting it, and I added a 1:1 transformer to one of the outputs which provides a ground isolation and eliminates any possibility of a ground loop. If you go the 2 amps together route, running one amp with whatever effects you might like such as delay or 'verb and the other dry is a good way to go. I sometimes like to use my Kalamazoo Model 2 together with a larger amp and turn on the 'Zoo's tremelo--trippy!

I use a "Y", with a break in the screen connection that connects the line out with the line in. I've never had any ground hum problems with this set up.

I use it for medium-large venues, running into a Marble Max with a little extra ummph from my Pro Junior. I find the line-out or even a mic'ing up of the Max can be a little harsh, but a blend with the Pro Junior sweetens it up.

I have tried this by using an electrical box with three jacks in it. I got that ground hum thing happening. I'll have to look into that jayphat idea.
