Are you looking to pick up a pure guitar, bass, or electric piano signal with all its brilliance and without any tonal alterations? An active DI box offers the best solution - as long as it has the same high-quality construction as the Palmer havel. The havel's low-noise active circuitry allows a higher input impedance than a passive DI box. This means the sound of the instrument is captured without treble or bass losses. High-level input impedance is especially important in interaction with the magnetic pickups in electrical guitars, electric basses and electromechanical electric pianos (e.g. Rhodes), as well as with (passive) piezo pickups for acoustic instruments. However, the Palmer havel is also very well suited to synthesisers and other electronic keyboards, since it offers enough headroom to handle even high-level inputs without unwanted distortion.  

Of course, the Palmer havel features a THRU output to pass the input signal on to the instrument amplifier. With 30 dB of pre-attenuation activated, the Palmer havel can also be looped in between the amplifier output and the loudspeaker, if you want to include the sound of the amplifier instead of the “raw” instrument signal. 

The balanced, low-impedance output signal from the Palmer havel is resistant to interference, which enables long cable runs without any loss of sound quality. Thanks to the built-in transformer, the XLR output is galvanically isolated. Any hum loops that may occur can easily be remedied by pressing the ground lift switch. For a power supply, a 48V phantom power unit or a standard 9V battery can be used. 

We're sure you’ve spent a long time searching for YOUR sound, and have invested a lot of time and money to get your instrument to sound the way it should. The Palmer havel transmits your sound faithfully and free of interference. This means your sound reaches the listener exactly as nature intended!

Love these socks!
The wife struggles with socks. She only like the Nike ones, then they discontinued them, so had to start the search again! Found these, they are expensive just like the Nike, but the size is true, they look great, they are super soft and stretchy. They are light weight and breathable and seem to wick away moisture. She loves these!

I stay on your foot they don’t slip in your shoe
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
This is the only socks I wear Under Armour because they stay in place I wear a size 8, but they’re more comfortable with a large instead of a medium, but I wear both because I have them already and you can pull them to stretch them out a little bit

Great fit, truly doesn’t slide off heel
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium, Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
I’ve scoured all the lands looking for a no-show sock that was 1) thin, 2) quality, soft, breathable material, 3) didn’t dig into my feet/heels, 4) doesn’t shrink, and most importantly 5) stays on the back of my heel without a bulky non-slip rubber piece and these check all the boxes! Perfect for low profile women’s work shoes like Keds, etc. Not low enough for most flats though. I wear a women’s size 9.

So good - I’m buying MORE.
Number of Items: 3, Color: White (3-pairs), Size: Medium
I’m gonna give you more detail than you need about why I’m buying these socks again. I’ve been the mom of girl athletes. I’ve been a model and a fashion director. I’ve worn every brand of shoe on the planet and never found a shoe that did NOT find a vulnerable spot on my foot to rub raw. Even my beloved white Jack Purcell sneakers. With that said - I don’t like socks. I’ve bought a TON of them in 35+ years.....all major brands. They shift. They lose their shape. They get holes in them and wear out too fast. Not these. I retired this year, and knowing I’d be in sneakers a lot, traveling, sightseeing ...... I bought these 6 months ago and have worn them constantly. I’ve traveled with them. I’ve washed them in hot water and bleach. The socks are like brand new. They are exactly the right cut so as not to be seen in a basic sneaker. The little silicone patch on the heel stays put. Not once have I had to dig down into my shoe and pull the sock back up. The socks have stayed soft and EXACTLY the same as the day they were new. Like I said - I am back to buy them again. Great quality!
