Cheap Douk Amp

Hi b
Do you think this might work as a guitar amp ?

I remember someone using the Mic input on something similar
(ie another low priced HiFi amp with a Mic input)

There was a lot of good information on impedance
etc in a thread Teresa while ago
But I can't find that thread now ....

I couldn’t open that Amazon page on my tablet - it kept trying to move my Amazon app’s default location to the UK, which I don’t want to do. So I don’t know which Douk has caught your interest. But the info below should help you….

I bought an inexpensive Pyle class D integrated amp ($33 last year when I got mine, now $50 on Amazon US) - here’s one of the threads on it. I also bought a Douk ST01 (which does not have mic preamps) at the time because I was testing and evaluating them for an article I wrote for audiophilestyle.com on class D amplification.

The Pyle has mic inputs for karaoke, so I plugged in a guitar and discovered that it’s pretty good. As long as the input impedance and sensitivity are right, a guitar will drive any of these. And a pedal with high enough output will drive the line or aux input(s) if impedance and sensitivity are right.

At 100W into 8 ohms, the Pyle was fine on a gig, driving a pair of Toob Metros. The push terminals for speaker wires are not as easy and strong as the 1/4” jacks we’re used to, so they’re more easily disconnected and a bit awkward on a gig. But for home use, they work great and sound decent.

many thanks Never
appreciate it ….

These cheap amps don't usually have specs for
Input Z and sensitivity on the aux or Mic inputs ....

So I was encouraged by your experience of
Plugging a guitar into the Mic input

I need the smaller form factor of one of this type


So guess I'll have to take a punt on it ....

I'll only be driving one speaker ,
Do you think I'll blow it up running the other output unterminated ?

Hmmmm ....
Alternatively I could use a small pedal board type amp
Which might be safer

Maybe a Quilter micro block or similar

I have a BluGuitar Amp1 (expensive), and a TC Bam200 (bass amp, $179). Both are very small, and work great for jazz tones, although the TC doesn't have reverb and doesn't do anything but clean w/o pedals.

I wouldn't take the chance. Without a signal on the channel, you don't need to dissipate much energy, you just need a load to stabilize the output stage. The easiest solution is to stick a small wirewound resistor into the speaker terminals - a 5 watt rating should be more than adequate. Feel the resistor after playing for a few minutes. If it's more than barely warm, go up to a 10 watt. An 8 Ohm 10 watt wirewound resistor is about $2 from Parts Express.
