Handmade MarmaladAmp guitar combo amp

1 Watt Above All!

While supplies last... Currently 5 pieces available!

The product has a dual purpose: a compact, always-ready practice combo that is portable and takes only a few seconds to set up. Ideal for very busy guitarists, new moms/dads, or anyone with lots of riff/solo ideas. It also looks good and is even fun. However, don't underestimate it; the volume knob isn't just for decoration; it was truly necessary to make the device so expensive during development. It's often misleading how many watts something has. It's worth trying this little one just because you won't believe that this single watt is loud enough to make a conversation impossible in a small room.
Product development started around October last year and has evolved into its current state by now (March 2016). Unfortunately, there will be no mass production, so we can consider it a limited edition, personally dedicated by the manufacturer!

For sale: (several pieces) a truly single-watt, single-channel practice guitar combo and an ornament for your room. I still haven't found a name for it, you can even submit ideas for that.

Here are some names I've thought of so far:
MarmaladAmp = LekváRősítő in Hungarian (Marmalade Amplifier),
Metálbefőtt (Metal Compote),
Rockfagott (explanation: 'üveg' = bottle in a slang context, and 'faggot' in English, which has strong sexual connotations and is quite negative towards the product... however, it loses its edge if written as 'fagott' as a musical instrument... sophisticated and cunning!).

Specifications:
Ingress Protection: IP 40 (protection against solid objects larger than 2.5 mm, not protected against water, so it's not advisable to play guitar under the shower with it, nor in a sandbox).
Power Supply: 6LR61 battery 9V (can be powered by 6-12 V), delivers 1 Watt at 12 Volts.
3 Watt speaker, for destructive mids and some low-end.
Battery replacement is possible after removing the cover.
Operating time: 12-18 hours depending on the battery.
Power amplifier IC: LM381N-1
Preamp IC: TL071
1 input
1 volume control (believe it or not, you'll need it; this is a beast that needs to be tamed)
1 tone control, or rather, a distortion gain control.

No switch is needed; it's always ready and just waiting for you to plug in your guitar jack!

The price might seem high at first, but it includes shipping, and I can only send it as a fragile package...

Here is a very unfavorable video recording of it in operation:

The recording was made with a Canon 550D camera, about 1.5 meters away from the amplifier, using the Canon's own microphone.
I will make more audio recordings soon; any help with that would be appreciated!

Note:
The prior art belongs to a Welsh "inventor"; unfortunately, I was late with my idea, though not by much... however, he has not filed any patents, so I can freely market my product.
However, if you would prefer to order from him (for 25 GBP + 10 GBP shipping), here is his contact: www.facebook.com
Although I don't know his exact specifications, he also used an LM386 power amplifier IC, but without a preamp, gain, or volume control. However, it has an output that can significantly overdrive any amplifier, so it can also be used as a very simple overdrive.
