Ashdown ABM 500 EVO II Head

(Ashdown references)

The amp is biventilé, preamp with a lamp that can be adjusted.

The power output is 575W at 4 ohm so we must avoisinner the 350 into 8 ohm.

Connector Jack / XLR cable or enclosure link.
By a single output against baffle (speaker jack or cable), connect the speakers in series then if you want to put in more.

As he stated above, there are three potentiometers (low, medium, high) and a 4-band equalizer through. All very nice, reacts very well to the slightest movement.
Otherwise there is tt what to issue an output + input-output effects loop and tuner.

Ashdown design "retro" it seems to be a passenger locomotive ds ... Super nice, with a view meter typical of the brand made in England giving his side a little retro.

Amp almost entirely handmade, the great class, a titan of strength (it is surrounded by a kind of flight case): a real tank.


I have not used the manual, the guy's music store where I bought me and I was generally explained quite simply!

The Plugg and Play: The sound is just beautiful ... Round, warm, punchy, well-groomed.
We do whatever we want with this amp. However, I have a preference for the Shape, less cramped, but everything is a matter of trimming.
Any lower rings of hell on that, the crust at 100 euros to the best Jazz bass.


I think this amp is for all styles because you get all the sounds you want! Always with this magnitude is not without thinking about Trace Elliot fire (hence the Ashdown engineers come from elsewhere).

I plugged my Warwick ROCKBASS in two minutes and I found all the sounds I needed!

Lack of resources I use a Behringer BA 115 cabinet that I changed to a Celestion BL15 HP, and it sounds great my faith. I had tried the equivalent Gallien Kruger and I liked much less.
I think even complete the set with a BA baffle 210 (which I will surely change the same treatment from HP).

I use mostly sounds pretty serious (which remain clear in the treble that said) and with a bit of Octaver for low infra ... A feast. This gives her a present but not "strong" not drunk.
The amp sounds regardless of the volume!


I own this amp for six months at the moment and frankly I do not see anything special against him. Amp noted for its price (I paid 958euros).

This mark is actually too little known, but given the quality of the product, it will not last and the most competitive prices I'm afraid. So do not hesitate! I would definitely do it again this choice, the price / quality ratio is outstanding, the same price an Ampeg not sound like that.

Ashdown ABM 500 EVO II Head
I will speak here of my setup complte:

- ABM 500 EVO II (575W with prampli lamps, equalizer and sub-octave)
- ABM 410 (subwoofer 650w into 4 ohms, with 4x HP 10-inch + tweeter)
- ABM 115 (subwoofer 300W into 4 ohms, with 1x HP 15 inches).

2 years, I use an ABM 500 EVO II, and a religious one ABM410 ABM115.
The three are reread in a daisy chain, the receiver does not have two exits, but both chambers have two jacks in parallle 6.35 (a Speakon connector is also available in rear).

I pay all of around 1600 euros, APRS have various combinations court carefully Ampeg / Hartke in this price range.
It is mostly the roundness and warmth of the amp to me sduit; may be as, I confess, the sub-octave Intgr which allows you to add a (small or large) pinc e major from an octave on the treble strings infrieur.

The ABM 500, the possibility of adding an element of pramplification lamps can make the grain more aggressive sound. It's weird, but it's the opposite of what feeling on my amp audiophile lamps (which sound much rounder and warmer than a transistor amp.

If the configuration ABM500 + ABM410 enough (I limit myself to gnralement dplacement of these monsters), reinforces the ABM115 really well in infrasound.

As one might expect this level of benefits, no vibration noise, nothing but deep bass and powerful. Not to be used only derrire an amp, but in complment to reinforce the bass ABM410 The tweeter has a central (not available to the ABM115), which has a real function in the reproduction of the attack of the strings and the dynamics of sound.

Irrprochable finish (his weight is confirmed) - the envelope is even buffalo leather!






Not having had the opportunity to tap into a pattern of better quality than mine, I think I would do without a doubt the choice.

Ashdown ABM 500 EVO II Head
I personally use version III of the ABM. This présernte just more compressed compared to the ABM EVO II.
Power: 575 watts into 8 ohms (or with 2 cabs)
conncectique presents: 2 output jack / Speakon, + 1 x front line pre / post. An instrument input, an effects loop, tuner output.
setting and the same effect as the EVO II except compression and more, as indicated above: a push button with a knob of level of effect.
In short, personally, it does lack a pedal member to manage the effects on stage, as the boost basa, preamp, compression ... The rest is very comprehensive.


Config surper simple, it connects you turn 2, 3 buttons, and it was the sound!
Manual? What for? Maybe just not to make dumpling at the connector?


It is perfect for my style of music (from rock to hard fities modern pop through!)
I utilitse with a jazz bass and a complement to ME50B qques effects
J'arrieve to find a sound is modern, well fatty, hot or very funcky ... so a very large variation possible!


I useful since about 1 year
I chose this amp for its sound, especially with coparaison ampeg SVT, which I found less persuasive. But this is only a personal opinion
If I had to redo a choice of amp, I'll put in balance with bass and orange mark ... But I do not regret my choice, even if I had the problem for rammener connection: Yune output speakondefficiente
