Jason Jason, you can get most Weber attenuators for under $225.00. The one above mentioned was $70.00. At 225.00 it would handle a 100w head and just about any cabinet you plugged into. Everybody else is just way overprice and looks like less features and from reviews these are better quality.]]> Live Sound Sin City Sid https://guitarnoise.forum/live-sound/epiphone-valve-jr-head-trigger-cab/paged/2/#post-286346 https://guitarnoise.forum/live-sound/epiphone-valve-jr-head-trigger-cab/#post-286321 Wed, 26 Mar 2008 03:51:20 +0000

The 5W from the Valve Junior shouldn't be stressing it at all.

Since it's just resistive and not inductive like a speaker it will colour the tone some. That's where something like the Weber Micromass which uses a speaker motor (speaker without a cone) would possibly be a plus (depending on how you like the tone). You might be able to slip a bypass cap into the RadioShack volume control circuit to stop the high frequencies being rolled off more - maybe make the capacitor switchable.

Edit - Wait a minute. As I looked at the spec a little more closely the picture seems to show a transformer of some type. That might help with the tone not being rolled off. Can anybody with one of these confirm that there is a transformer in there? Pretty schweet idea.

Instead of a project box I bet you could use one of those plastic electrical boxes for in wall switches to hold this. You can find those at any home remodeling store (Loews, Home Depot, etc). It will be a perfect fit and you would be able to easily drill holes for the jacks.]]> Live Sound Hyperborea https://guitarnoise.forum/live-sound/epiphone-valve-jr-head-trigger-cab/#post-286252 https://guitarnoise.forum/live-sound/epiphone-valve-jr-head-trigger-cab/#post-286231 Tue, 25 Mar 2008 19:42:18 +0000 https://taweber.powweb.com/weber/micromass.htm Well, it's worked fine for me for over a year. I know of a couple of other members here that have buit & used it with their Epi Valve Jr's as well.

Dan Interesting, I figured that thing would get real hot. I didn't see any specs on it that pertained to its load carring capacity.

I was acutally thinking about buying the EP and that attenuator just for its ability to adjust tone and speaker load but the tone wasn't for me.]]> Live Sound Sin City Sid https://guitarnoise.forum/live-sound/epiphone-valve-jr-head-trigger-cab/#post-286231 https://guitarnoise.forum/live-sound/epiphone-valve-jr-head-trigger-cab/#post-286217 Tue, 25 Mar 2008 19:07:58 +0000 https://taweber.powweb.com/weber/micromass.htm Well, it's worked fine for me for over a year.

Hyper, you may be right. Just a slight twitch to the knob and it was WAY louder. Not as much later on the dial. That would make sense.

Been playing on this sweet amp this evening. My ears are ringing right now 'cause I was playing a little louder than I should (the wife is out). :twisted:

Looks like the valve junior site is gone, and I can't find the thread on here. Very easy to make though. You'll need:

2 1/4" Mono Phone Jacks (Radio Shack # 274-275)



In-Wall Mono Volume Control (Radio Shack # 40-993)





Some speaker wire - I used 16 Guage (Radio Shack #278-1267)



Some solder & iron, or whatever you want to use to connect the speaker wire to the phone jacks and volume control. I think I just stripped the plastic off the wire ends, twirled it around the contacts, and put electrical tape on them. :oops: Remember to connect + to + & - to-

A project box to put it in ( I used Radio Shack # 270-1805, although 2" deep isn't quite enough, so I used spacers & electrical tape to seal it up. If you can find a 3" deep one it would be perfect.) The plastic project boxes are easy to cut. I cut out the top enough to drop the volume control into, and made holes on each end to install the phone jacks.



anothet short speaker cable to connect to your speaker cab.

I put mine together in a couple of hours with limited tools, and it works like a charm.

Hope that helps.

I've also got a Valve Jr. Head and the matching 1x12 cab. I bought mine used (very, very lightly) from Craig's list for about as much as the combo goes for new - great deal. It's been a great little practice amp. I use it though my Weber attenuator that I originally bought for my Traynor YGM-3 that also gets used at home (a different sound than the Valve Jr.).]]> Live Sound Hyperborea https://guitarnoise.forum/live-sound/epiphone-valve-jr-head-trigger-cab/#post-286062
