Got me one of them Aiken's

I used to have an Aiken Invader 18 watt combo, lovely amp, that I gave up in a trade in a huge downsizing thing I did. It was a sweet amp. I started by putting all the tone controls at 12 o'clock and going from there. Honestly I couldn't get a bad tone no matter what I did! Does yours have the plexi/alum switch? I found my LP's worked the best on alum setting and single coil guitars on the plexi setting. Play around and have fun, they are great amps!!!!

Al, I have a 30w Intruder. You will find (actually you have already found) that the master has a very gradual taper. You get the best chunk and thump with the master between1 and 3 o'clock with 3 o'clock being pretty much full output.

Running in plexi mode will be darker, thicker and ali will be brighter. Blending the 2 volumes controls will give a wide variety of tones. Try volume 2 (dark) at 11 o'clock and volume 1 at 9 o'clock for starters. This should get you to generic marshall land. I have found that the bass/tone controls do not have a large impact, they seem to operate in a fairly narrow range.

Twist the knobs and enjoy. Its a great amp.

Aiken amps are very open and revealing of any mismatches or "inferior" gear anywhere along the line.

My guess is,since the Cornford cab is both front loaded and has a V30-the one speaker the amp simply won't tolerate-that the problem lies there.

Also,a booster instead of an overdrive would react better.The amp has a pretty distinctive overdrive character to begin with,so the pedal mars it to some extent...and you can hear that.
If you intend to use the amp with pedals though,try maxing the master and limiting the preamp volumes.This way your amp becomes a BIG "monitor"amp.

The master on the Aiken is really great...but that,by master greatness standards,means that it doesn't colour the sound or eat up frequencies.It doesn't cater for-nor does any master for that matter-for the added response and compression of a hard working power amp.

When I want to practice with the Intruder 30,I still use the Weber mini Mass-straight or parallel-and turn the master really high...all the way actually ,so it's out of the circuit.The meanest crunch in my life instantly appears and when you step on a booster...beware!

Now all that would apply,assuming the amp runs as it was supposed to run...Have you checked the bias?

Lastly,tube selection,especially the output tubes,play an ever important role in the final outcome.If the amp is equipped with Svetlanas(or winged C's)you might find "them" a little harsh.Many people do,although these particular tubes exhibit other desirable traits.You might then want to try JJ's or another variant and also experiment with the preamp tubes.The JJ's that are in there, assuming the amp is stock,become slightly darker and smooth out-compress when driven hard only(short plates).

Best of luck!

Hi, Al,

First of all, I'm sorry you are not happy with the amp. I've not heard Intruders described as fizzy or quiet, especially the 30W models, as they can get very loud.

One thing to check: the Intruder uses a standard Marshall-style Cliff jack for the effects loop. It has switching contacts that turn the loop off when nothing is plugged in. I recently had an amp returned for repair that sounded thin and low volume, sort of like a transistor radio. It turned out to be a bad jack - the shorting connection was a bit out of kilter, and was barely making connection. Replacing the jack fixed the problem. You might try plugging a cable into the effects loop jack and removing it to see if that joggles anything (or, if you have a stereo cable, plug it in and short the tip/ring together to see if that improves anything.

Another thing - use of Vintage 30's with any Aiken amp voids the warranty. Actually, they do tend to sound harsh to my ears. The best speaker is a Greenback. If you have any way to try the amp though a cab with Greenbacks, you should be able to tell whether it sounds properly "Marshally".

Another problem could be the tubes - if you have a set that you can swap out, give that a try.

If all else fails, you can send it to me and I'll be glad to look it over at no charge and ship it back to you.

Thanks,

Randall Aiken

 

Plug it into a 2x12 with greenbacks, forget the pedals because the amps natural overdrive is good on its own, and crank it up.

I'm sure it will be fine.

 

I'll bring my greenback loaded 4x12 round to yours soon so we can test the thing out.

 

The presence control on that amp is actually a cut control, like on a Vox, but voiced a bit higher in frequency. You should be able to get it rather dark by turning it all the way anti-clockwise. Did you guy the amp new or used? I think the first few had the original style presence control and we changed to the cut control to improve the tone.

Greenbacks are definitely smoother in the high end than G12H30's, particularly if they are later model Chinese ones, at least, in my experience (I quit using them because they started to sound harsh).

Do you get the harshness when both volumes are at 9am? Is it only when the amp is crunching up?

Sounds to me like some sort of tube issue.

 

Number 0006 should have it. In fact, I think they all did except for number 0001 that got stolen at NAMM, but I could be wrong (my memory isn't what it used to be!). It's easy enough to tell, though - open it up, look at the back of the presence control pot and check it's value. If it is a 5K pot, it's the original presence control, if it is a 1Meg pot, it is the new one. Also, if you like, you can email me a picture of the inside and I can tell you if it is right. Again, if not, I'll be glad to mod it at no charge to you.

Thanks,

Randall Aiken

 

I own 3 Aikens-A Tomcat, a 30 watt Intruder, and a Sabre-Simply amazing amps, and Randall Aiken is a true Gentleman-Keep playing with the controls-It's well worth it-I love all of mine-Try your Intruder with 2 Blues in an oversized 2x12 cab-Incredible tone!!
