潮濕及干燥天氣時對古典吉他的保養(yǎng)
大多數(shù)吉他愛好者在潮濕天氣時均會覺得吉他的聲音不如干燥時,故會往吉他盒里放干燥劑,或在房間內加強抽濕設備。但有時有效有時卻無效,應該看是什么因素影響音色再針對原因來解決。以下是作者的經驗,供大家參考。
一、首先要知道木材在濕度高的情況下重量會增加,硬度會降低,木紋橫向的體積會加大,這些情況都會對吉他音色造成影響。其中前兩種情況對白松(Spurce)或紅松(Cedar)會造成相同的影響,高音亮度降低,低音變暗啞,但這些均不會造成永久性的改變,到干燥的季節(jié)時,通常都會恢復正常。在潮濕天氣時大家可以選用直徑較細的弦線,一般情況下如維持相同的拉力,直徑較細弦線的音色會較尖,在一定程度上可以補償高音的光輝及低音的亮度,這類弦線主要是以高密度的尼龍或纖維代替常用的尼龍,常見的有法國SAVAREZ牌的Alliance型號、美國D’Addario牌的C系Pro.Arte型、日本的Cecilia,奧地利的Dominant等。由于一般琴均是高音受影響較多,故也可考慮只換高音弦,以免對平常的彈奏習慣有太大影響。
至于橫向體積變大的問題卻復雜得多,以筆者實際工作經驗,足夠干燥的紅松(Cedar)基本上不會產生太大問題,但白松(Spurce)的問題卻嚴重及復雜得多,若不作特別處理,即使十多年的木材也不成,在工)一中可以看到紅松的面板材料沒有太大變化,但白松有可能從微拱2mm變成下陷4一5mm。但白松(spurce)面板的吉他一般均設計成微拱1一2mm,否則音色、音量均會較差。解決的辦法是盡量注意吉他的’干燥,不彈奏時擦干放回琴盒,有需要換弦時要續(xù)根更換(即卸下一根弦換上一根弦,切勿同時卸下6根,再同時換上6根),平時彈奏后有松弦習慣的應避免或減少松弦的程度,以保持一定的拉力(這些情況在千燥時卻并非絕對必需),由于面板的弧度若長時間有變,很容易對吉他的音色造成永久性的損壞。
二、在一般情況下潮濕天氣對吉他的影響只是暫時性的,氣候干燥時便會恢復,但過份干燥對吉他的損壞卻常常是永久性的,主要受影響的部分是指板、面板,背板及琴身與琴頸連接的地方,細心的愛好者可能會發(fā)覺所有受影響的部分均有一面接觸空氣,由于水分從木材逸出后木材不可避免地會收縮,指板征收縮時會發(fā)生的問題有兩方面,一為變形二為音品線離位,指板變形會造成手感變差及碰品,而音品線突出指板,會令彈奏時不舒服,嚴重時更可能把手指割傷。不論哪一種均會造成彈奏困難及不便,要修理的話便要把品線取下,重新磨平指板,再把品線重裝,這些均要專業(yè)人員去做。要預先避免這些情形可于清潔指板后再用油涂在指板上,可使用的油類為阿麻仁油、橄欖油或本管樂器油,一般涂上后待一兩小時后再抹干。多長時間才再涂要根據(jù)日常彈奏多少來定。
吉他若長時間暴露于極干燥的環(huán)境之中,面板及背板有可能因過度收縮而裂開,這些是自己無法修理的。指板以外的地方我們也不能涂油,要從兩方面著手解決:一是維持周出環(huán)境的濕度。最好是在室內使用加濕器。避免將吉他放置在暖氣設備旁;不要于戶外長時間彈奏,彈奏后立即放回盒內或袋中;另一辦法是維持吉他本身的濕度。在國外有專用的設備出售,但我們也可以自己動手制作。先找一根較粗的塑料吸管,裁成約10公分長,管中塞進海綿,再用針在吸管上扎上多個小孔,縛卜繩子方便操作,待塑料吸管中的海綿吸進水后冉從音孔懸空放進琴內,注意不要吸進過多的水分,以免有水滴出,特覺得水分放出的速度不對,可通過調整小孔的大小及多少來控制。由于材料個難找到也很便宜,故可多做幾個不一樣的,以找出最合用的。
以上方法希望能對大家有所啟發(fā)到拋磚引玉的作用。
If there probably is one thing that I have learned on this every day life is one doesn't bought it. It ca be alleviate by you unexpectedly or getting ready. Therefore, in no way think twice to exhibit your fondness and adore. Walking out to years ago, my good friend Gina traveled to my office environment hunting quite haggard and staring blankly within the wall structure.
Specialists her how it happened and her solution truly shattered my cardiovascular system. “My hubby passed on of swing last week, it had become all so immediate and that i never can deal.” She paused for a little bit and continued… “If only I could have taken care of him far more maybe this wouldn’t received occurred.
It's possible basically advised him of his treatment or give magnitude to his diet program however always be below here. Irrrve never even exhibited him the romance that he or she should have had it had become all so sudden…” she appeared moping and crying until eventually she are unable to talk nowadays. I gave her the most important larg and exhibited her my greatest sympathies.
Repent is definitely an distressing sensation to obtain. Healthy for you if you had the opportunity receive and may well avoid from using it but what should you in no way get that likelihood, during Gina’s instance? So previous to its too far gone, present your fondness due to the fact what comes after be sorry for is sense of guilt and sense of guilt can do lots of deterioration with your effectively-staying perhaps living.
So here are some ticklers concerning how to present your fondness. To point out your fondness never perspire the tiny things or mess it up up. Without a doubt, it can be quite annoying if he isn't going to position the toilet take a moment or the way he messed up your garage or how his snoring loudly will keep you awake in the evening.
But they are the items which can be treated it with in a delicate method building your spouse feel unhealthy because of these little items can be quite unwanted. Be polite and give lots of regard, listen closely far more, SELL hermes plume shoulder bags it is funny that you someday handle your cashier perhaps financial institution teller with a lot more regard than your husband or wife.
Be safer than necessary to your spouse. An additional way to present your fondness is simply by not implementing your husband or wife without any consideration. Remember his special birthday, you never know it is the final the one that he’s gonna have. Manage him- if your hubby likes to feed on, provide him his preferred meal, purchase him new undergarments (adult men as a rule have almost no time just for this) or maybe take action wonderful.
To point out your fondness, you'll want to be able to absolve. If he executed you inappropriate. Speak to one another and be able to compromise. If you be able to absolve then let him know so and produce correct layout, never continue to keep him amongst people and commit the following 10 years of your respective married life acquiring even or alienating him.
Start to see the goodness in each other. Men and women do and may transform for any far better. It's actually just unhappy that often people see the goodness of their lover when they're presently absent. It's actually crazy that often persons give far more regard in the event the individual is presently expended as opposed to he or she is lifestyle.
It's actually satirical that often a lot of people get pleasure from their lover far more as he is dead as opposed to he or she is alive. Take my words and phrases as he is dead, the silence in your own home may be incredible and the residence that you wipe out to generally be very tidy might be useless without the need of his clutter.
Yet again present your fondness because you can- larg far more, hug far more, say I enjoy you far more due to the fact it'll be a really disaster when you finally hugged him but he are unable to larg you back. To point out your fondness attempt to take into consideration that each and every minute that you commit to him may be the final minute.
Seize the afternoon and grab your ex girlfriend. Exhibit your fondness, never hold back.
