I played the Mini Recto when I was looking for a replacement of my Carvin V3M (grew tired of its fizzy/flubby high gains)
.
The Mini Recto sounded flubby in the gains (nice, characterful cleans though), and when I then played an Engl Ironball, the difference was night and day. Bought the Ironball on the spot. Sold the V3M soon after.
Here's two decent comparisons of the Mini Recto vs. the Ironball (notice how the low-end of the Engl won't turn to mud
Fast forward 2 years and after a stint with a Mesa Mark IV (full sized, Rev A) I missed the Mesa Mark cleans and gain. Found a reasonable deal on a Mark V Mini and bought that, after just hearing the Crunch channel.
Still have the Ironball too.
They both have their strengths and commonalities (about 16lbs, 2x EL84)
Engl Ironball pro's:
-Engl full tube tone in small package (no gimmicky toy)
-footswitchable gain-boost
-footswitchable reverb
-footswitchable master volume boost (fixed, but a great interval for at home playing for a lead boost)
-4 different gain levels available on footswitch (2 channels, each with gain boost on/off)
-good master volume (next to a seperate lead channel volume, so that you can crank the clean channel as well)
-tight, in between Marshall-esque tones achievable too
-nice sounding digital reverb
-very useable powersoak (20W, 5W, 1W, Off (for direct recording)
Engl Ironball cons:
-clean is nice, but not in the same league as Mark V:25 cleans
-no footswitchable fx-loop
Mesa Mark V:25 pro's:
-Mesa full tube tone in small package
-best clean tones of any micro/mini head (IMO)
-awesome crunch mode on 1st channel
-graphic EQ (footswitchable; although, since it would be always on, I rather had another function footswitchable)
-real spring reverb, but small tank (Engl's digital reverb sounds slightly better and more useable, from mild to Malmsteen)
-seperate reverb controls per channel
-great high gain tones in both Mark IV and Xtreme mode.
Mesa Mark V:25 cons:
-since graphic EQ is pretty much always necessary to counter the excessive middy character, having that footswitchable isn't really helpful
-no footswitchable fx-loop
-very finnicky channel volumes (gets real loud real fast)
-has a pretty loud/noisy fan (I replaced that on mine...now it's totally silent)
I've gigged with the Ironball (and a 2x12 or 4x12), not yet with the Mark V:25. But for home(studio) stuff, they work nicely.
